What is methane?
Methane is one type of chemical compound in which it indicate CH4 as a chemical formula. Methane has single carbon and four hydrogen atom attached with a single bonds, it mean 4 hydrogen attached to Carbon with single bonds. If single bonds are attached. therefore It is called alkane.
Single bonds indicate – alkane
Double bonds indicate – alkene
it is make a group with 14 hydride. it work as a natural gas. Methane is a simple called hydrocarbon. It has one carbon atoms and four hydrogen atoms.

CH4 polar or nonpolar?
Here, we will discuss about, why ch4 polar or nonpolar?
first off all, you look the lewis structure of ch4.
If you see with carefully on lewis structure of methane (CH4) in which carbon is a central atoms and sharing electrons which have 4 hydrogen.
If you see the shape of methane molecules you could get a quaite symmetrical molecules because the hydrogen items are sprayed out and avoid the repulsive forces. So, the shap of this molecules is symmetrical. it mean, the arrangements of this compound is a quite symmetrical.
“Molecules that has symmetrical and that has no any loan pair that are non polar molecules“.
methane CH4, molecules has no any loan pair, so it look like a symmetrical compound. it is known as non polar molecules.
Therefore, it is conform that this compound is totally Symatrical with the shape of this molecules.
If you talking about Electronegativity of this compound, in this case, hydrogen and carbon has less Electronegativity.
It mean there is properly attraction between molecules. but not proper attraction between carbon and hydrogen.
So, we can say that there is no net dipole movement in this molecules. because of this shape and better arrangements of this molecules.
this molecules has not properly net dipole movement and has no properly charge distribution.
Therefore, CH4 Methane is non polar.
if any body asked, ch4 polar or non polar?
My answer is – ch4 is nonpolar molecules.
Net Dipole Moment
Meaning of overall net dipole moment is;
Di (means) – two
Poles (mean) – two pole, it mean, there are two poles, one is positive pole and other is negative pole.
Moment – it tells about the direction of poles.
Net dipole moment – the overall dipole moment of molecules is called net dipole moment.
Dipole moment – dipole moment tells about magnitude of charges and distance of center of charge. this is called dipole moment. dipole moment tells about polarity, and also tells about molecules is polar or non polar.
Net dipole moment of ch4 – first draw the structure of ch4 molecule (methane molecule).
According to structure, the center atom is carbon and four hydrogen is bound to it.
Carbon bonds are formed with four hydrogen and all hydrogen have equal sharing electron with carbon.
When we are having equal sharing electrons in molecules then there is no difference in electronegativity due to equal sharing.
When there is no difference of electrons, there was no polarity. in this case, dipole moment are always equal to zero.
In case of ch4 molecules, carbon is center atom and four hydrogen are attached to it. carbon has negative charge and four hydrogen has positive charge as shown in figure.
We know that carbon has more electronegativity as compair with hydrogen. that’s why the direction of arrow is from less electronegative to more electronegative.
We know that, due to high electronegativity the direction of arrow ➡ is towards the carbon.
they are cancelling each other’s effect due to arrow going in opposite direction. if you talk about upword and down word, there is no difference of electronegativity,
therefore, they are also cancelling each other’s effect due to arrow going in opposite direction.
Due to this, all effect are cancel out and net dipole will be zero.
finally, we can say that the net dipole moment of ch4 is zero.
Formation of CH4
you know that, ch4 (methane) is formed with one carbon and four hydrogen.
the atomic number of ch4 is 6. and its configuration is 2,4. carbon has 2 electron in its inner cell. and 4 electron in its outer cell.
CH4 has four hydrogen, and each of four hydrogen has one electron. as shown in figure.
this mean that carbon has four electrons in its outer cell to complete the octal of its outer cell. and hydrogen also needs one electron to complete its dopplate.
Hydrogen will shere one electron with the electron that are present around the carbon. as shown in figure.
there are four hydrogens, four hydrogen will take one electron and shere their electron with each of the carbon atoms.
and this will make the four hydrogen have two – two electrons, which will form a pair of electron and a single bond. as shown in figure.
now, will be connected by single bond between carbon and hydrogen.
as a results, that bonding of single bond will form ch4 molecules.
Molecular Geometry of ch4
First draw the Lewis structure of ch4
You can explain with the help of AXN formula.
A – Main atoms
X – chemical bonding atoms
N – Non bonding pair
In this case, there is no any non bonding pair.
So, its cancel out
take only AX4 for explanation,
If you look in the perodic table you identify final molecular geometry.
AX4 – tetrahidle
therefore, molecular geometry of ch4 is tetrahidle.
Electron geometry for ch4
the electron geometry of ch4 is tetrahidle just because there is no any loan pair.
Supposed, if loan pair add, just look like thats the pair of electron are not between atoms and make a bond. but it is not any loan pair in ch4.
So, the molecular geometry is tetrahidle and electron geometry also be tetrahidle.
CH4 ionic or covalent
If you understand about ch4 ionic or covalent first you look in perodic table.
carbon atom is non matel and hydrogen is also non matel. it mean both are non matel.
two non matel is also called covalent compound. therefore, ch4 is a covalent compound.
Solubility of CH4
In ch4 molecules, carbon is center atoms and four hydrogen are connected with carbon.
the molecular geometry of ch4 is tetrahidle and electron geometry is also tetrahidle.
In case of ch4 molecules, there is small difference in electronegativity between carbon and hydrogen. but the hydrogen is connected different direction.
so, you can say that, ch4 is nonpolar but h2o is polar molecules.
Ch4 is not very much dissolved in water. only disolved 22.7 mg/L.
If more methane dissolved in water and if increase the temperature methane become less soluble. Similarly, for different other gases, such as
If temperature increase, they become less soluble.
It is soluble in other substance, such as
What is the intermolecular forces of CH4?
It is One type of forces in which it is made C-H bonds. this meam, it is not bonds dipole. because the electronegativities of c and h are so close.
Therefore, C-H bonds is called nonpolar and it has no bonds dipole. ch4 molecules are non polar, it has not dipole-dipole intraction. it has only london dispersion force. and ch4 molecules is not a dipole because there is no any negative pole and positive pole.
Due to this, it is not generated dipole dipole interaction. the central atoms carbon has no enough electronegative to made strong intermolecular forces. such as hydrogen bonds.
Carbon is not highly electronegative atoms that made a strongest bonds such as “hydrogen bonding “. there are few molecule are made hydrogen bonding. Such as nh3, h2O.
But if molecules make N-H bonds or H-O bonds. hydrogen bonds are generated between molecules but if hydrogen are directly bound in nitrogen or oxygen, fluoride.
According to methane structure or according to above discussion, can you say ch4 polar or nonpolar?
Yes, according to overall discussion, we can say that, ch4 is nonpolar because this molecules has no any dipole or there is no any poles (negative pole or positive pole) due to this reason, dipole dipole interaction is not possible, in this particular molecules (ch4).
So, there is no any dipole – dipole interaction occur in ch4 molecules. there is not good Electronegativity for make a strong intermolecular forces. such as hydrogen bonds or dipole dipole interaction.
Now, we can say clearly that, CH4 exist only London dispersion forces.
Yes it is true, there is not a big difference of Electronegativity between C and H. that why ch4 has not permanent dipoles dipole interaction. ch4 is a tetrahedral shape.
Frequently Question Answer
1. Why methane (ch4) has not dipole dipole interaction?
You know that, non polar molecules has not capable to make hydrogen bonding, and this type of molecules has not create dipole dipole interaction or dipole-dipole intermolecular forces.
If you talking about, “Electronegativity” the electronegativity of carbon and hydrogen are so close then it show the Electronegativity is very less between carbon and hydrogen. and it makes C-H bonds that are non polar. there is no create dipole bonds between molecules.
Therefore, we can say that, methane has not dipole dipole interaction.
2. What is the bonds of CH4 methane?
Actually, the methane is make C-H bonds. it mean this molecules has one carbon i and four hydrogen atoms held together.
the attachment of carbon-hydrogen, it make covalent bonds with the help of sharing of electrons. but this is bonds is non polar.
3. is CBr4 polar or nonpolar?
CBr4 Make C-Br bonds due to difference of electronegativity between molecules, such as carbon and Br4. In this molecules, carbon have more electronegativity compare to Br4.
If you talking about the Polarity of CBr4. this molecules is know as polar molecules. cBr4 have four regained electrons around the central atoms. it is called polar because the shape of molecules is symmetrical.
this molecules is symmetrical in shape, so that it is called as a polar molecules.
4. What is methane?
Methane is a type chemical compounds. the chemical formula of methane is ch4. it is colourless chemical compounds.
The chemical compound such as ch4 (methane) is not acidic. because hydrogen is boud directly to carbon. this compound ch4 (methane) is “neutral” as pH 7.
Methane compounds is odourless, colourless, and flammable gas.
It is mostly used for preparation of many organic chemical in chemical industry.
