CH3Cl intermolecular forces has dipole-dipole forces and London dispersion forces.the chemical name of CH3Cl is chloromethane.

Hello, reders today we will discuss about what is the intermolecular forces of ch3cl and polarity

I have made this guide to help you out. So, hold your seat and be with the end of guide.

So, you could get valuable information out of it.

CH3Cl intermolecular forces


The chemical name of this compound is chloromethane. If you see properly the structure of chloromethane, carbon with the three hydrogen (ch3) and chlorine (Cl) are attached to it. and charge between carbon hydrogen, it is form C-H (carbon- hydrogen) bonds. that this bonds is non polar. and it is also form C-Cl (carbon-chlorine) bonds. but this bonds is polar.

You know that, chlorine has more electronegative compare with carbon. due to this, it is make partial positive charge on carbon and partial negative charge on chlorine. due to this charge it interact each other and the direction of bond dipole between carbon and chlorine is upwards. It mean, it generate dipole moment between C-Cl and C-H. this type of intraction is called dipole-dipole intraction.

therefore, you can say that, ch3cl has dipole dipole intraction. and carbon-chlorine bonds are slightly stronger then carbon-hydrogen.

London dispersion forces

London dispersion forces occurs specially in non polar molecules. Consider the neutral atoms. In case of neutral atoms, electrons are equally distributed. You know that electron are constantly revolving around the neuclie. the structure of atoms are distributed as shown in figure.

London dispersion forces

Here, one side of atoms, there is more electrons, then it make partial negative because it contains more electrons and other side of atoms, there is less electron. So, it make partial positive charge because it contain less electrons. therefore, these type of intraction is called dipole-dipole intraction.

It has two types of pole.

1. Positive pole

2. Negative pole

this atoms also become a neutral atoms. So, we can say that it is temporary dipole.

temporary dipole:- Temporary dipole is a dipole when the electronic cloud neutral atoms is destroyed for the time being.

Dipole Moment in CH3Cl

first you draw the structure of ch3cl

First of all, i will explain about charge for C-Cl bonds and C-H bond.

charge between carbon and chlorine – chlorine has high electronegativity then carbon. So, chlorine has partial negative charge whereas carbon has partial positive charge.

charge between carbon and hydrogen – carbon has highly electronegativity then hydrogen. so, carbon has partial negative charge whereas, hydrogen has partial positive charge.

the direction of bond dipole between chlorine and carbon is upwards. similarly, the direction of bond dipole is same in carbon hydrogen. but some bond dipole is cancel out but overall the bond dipole is greater. therefore, you can say that, the net dipole moment is very good in ch3cl.

Ch3Cl Polar or Non Polar

You know that, dipole dipole interaction occurred in polar molecules. but how you can say that ch3cl is polar molecules or non polar molecules. lets get to now about it is “polar or non polar”.

CH3Cl is polar molecules because carbon are attached with three hydrogen, it is non polar, and london dispersion forces occurs non polar molecules but carbon – chlorine is polar molecules. because chlorine has more electronegative charge then carbon. So, it hold electron on it.

Types of intermolecular forces

Dipole-dipole forces

Dipole dipole forces occur between two polar molecules.

Dipole-dipole intraction are attracted among polarized molecules. we know that polarized molecules has two poles partial positive pole and partial negative pole.

Therefore, it is called dipole. dipole dipole intraction occur between two polarized molecules or between two polarized dipole.

Consider the one dipole, it has two pole partial positive pole and partial negative poles. consider another dipole it has also two poles, partial positive pole and partial negative poles, we has two dipoles. So, the negative pole of one molecules attracted the positive pole of another molecules. due to this, attractive forces are produces. this attractive forces is called dipole dipole intraction.

For example,

HCl Molecules

Yes, it is true dipole dipole forces are active between two molecules of HCl. these are the best example for dipole dipole forces.

Cl is highly electronegativity atoms compare with hydrogen.

That’s why, Cl has partial negative charge whereas, hydrogen has positive charge.

Due to this they attracted each other and dipole dipole forces are generated.

London dispersion forces

london dispersion forces mainly active in nonpolar molecules because this type nonpolar molecules has no any net dipole (poles).

This mean, there is no any partial positive charge and no any partial negative charge. So, there is no any intraction is done. Due to this this type of forces considered as a weakest intermolecular forces. london dispersion forces are a type of forces in which they attracted between atoms or molecule that are normally electrically symmetric. in this case electrons are symmetric distributed with respect of nucleus.

Hydrogen bonding

This type of bonding exist between the two polar molecules. this mean, hydrogen bonding occur only in permanent dipoles which intract between the partially positive charge ion in a molecules and the partially negative charge ion of another molecules.

For examples,


Hydrogen bonding are active between two polar molecules. It intract between two poles, one is partial positive poles and another is partial negative pole.

Another explanation of this is, when nitrogen atom are attached with high electronegative atom, such as oxygen, fluoride.

Hydrogen bonding are created when hydrogen make N-H bonds, N-O bonds or N-F bonds.


Hydrogen bonds occur when hydrogen are attached with very electronegative atoms such as, nitrogen, oxygen, F.

In other words, hydrogen bonding are created when if hydrogen make N-H bonds, N-O bonds or N-F bonds. You know that H2O is best example of hydrogen bonding intermolecular forces.

Oxygen is highly electronegativity atoms compare with hydrogen. Thats why hydrogen have partial positive charge and oxygen has partial negative charge.

Due to this, both atoms are attracted each other. and hydrogen bonding occur between polar molecules (h2o). and they make H-O bonds.

Ion ion force

Ion ion forces are one type of attractive forces between ion with positive charge. it is also consider as a ionic bonding.

This forces arise from electrostatic attraction between two ion with positive charges.

This type of forces is considered strongest intermolecular forces.

Question And Answer

1 What intermolecular forces is the most important between CH3Cl?

The most important intermolecular forces occur in CH3Cl is dipole dipole forces. It occur/active between two molecules of CH3Cl.

You know, dipole dipole forces are mainly active in polar molecules. CH3Cl molecules are a polar molecules.

Yes it is absolutely true, this type of interaction is possible only in polar molecules.

Dipole dipole forces are stronger then London dispersion forces. therefore, the most important intermolecular forces active between two molecules of CH3Cl is dipole dipole forces.

So, dipole dipole forces is know as a strongest intermolecular forces compare with London dispersion forces.

2. What are the types of intermolecular bonds?

There are 4 mejor type of intermolecular bonds are as follows,

Ionic bonds > Hydrogen bonding > Van der Waals dipole-dipole interactions > Van der Waals dispersion forces.

3. What type of intermolecular forces exist in gases?

Actually, gases have much lower densities. Very weakest intermolecular forces occur in case of gases compair with liquid or solids.

4. What types of intermolecular forces are persent in the following compounds?

(a) CCl4

Weakest intermolecular forces are persent in CCl4.

(b) (nh3)
