What is inorganic benzene?

Inorganic benzene is a polar inorganic Compound with the formula B3N3H6. it is called cyclic compound, In this cyclic Compound, three BH units and three NH units is connected alternate. the borazine Compound is isoelectronic and isostructure with benzene.

inorganic benzene is also known as borazine. We know that borazine is a polar inorganic Compound. So, it is more reactive whereas benzene is a non polar so they are less reactive.

Borazine structure are created with three B-H bond and NH bond. Borazine structure is cyclic in nature. Borazine is made from electron, so it is called isoelectronic structure.

The chemical formula of Inorganic benzene is

  1. B3N6H3
  2. B3N2H6
  3. BN3H6
  4. (BH)3(NH)3

the chemical formula of inorganic benzene is (BH)3 (NH)3. Inorganic benzene is a polar inorganic Compound with the formula (BH)3(NH)3.

Its cyclic compound where carbon in benzene replaced with boron (B) and nitrogen(N).

it is called organic compound and cyclic compound, In this cyclic compound, there are three BH units and three NH units is connected alternate.

yes, it is absolutely true, the inorganic benzene (borazine) compound is isoelectronic and isostructure with benzene.

inorganic benzene is more reactive whereas benzene is less reactive. reson is polarity.

You know that, polarity is difference between inorganic benzene and benzene. benzene is a non polar molecules that’s why it is less reactive. Whereas inorganic benzene is polar molecules so, it is more reactive.

Inorganic benzene is?

Borazine

We know that in case of inorganic benzene structure, inorganic benzene is also denoted with borazine because it is very similar to benzene structure. The main similarity is that, in case of borazine, there are B-H or B-N bond on it. Whereas in case of benzene, there are C-H or C-N bonds on it. and borazine is polar compound so it is more reactive but benzene is non polar so it is less reactive.

We know that, borazine is more reactive compound, it make cyclic structure and it make structure from electron so, it is called isoelectronic structure. borazine is also called isostructure, so it means it is similar to benzene structure so it is called isostructure. This structure is made with the help of B-H and N-H bond.

Properties of inorganic benzene

1. It is colourless liquid with aromatic smell.

2. This compound have cyclic structure.

3. Borazine have B=N (double) or B-N (single bond) but bond length are equal.

4. It make planner cyclic structure.

5. Borazine is more reactive then benzene.

6. In water, it is hydrolyzes to boric acid, ammonia, and hydrogen.

7. Bond length of borazine is 144pm.

8. It make isoelectronic structure

9. Borazine structure is same as benzene.

10. Borazine is also called benzene because both have cyclic structure.

How will you convert diborane into inorganic benzene?

Borazine was first prepared by Alfred stock and pohland in 1926 by the reaction between diborane and ammonia in 1:2 ratio.

Take diborane and ammonia in 1:2 ratio and heat at low temperature then it is given addition product like – B2H6. 2NH3.

B2H6 + 2NH3 – B2H6. 2NH3

When addition product B2H6. 2NH3 is heated at low temp (200°) a volatile compound inorganic benzene is formed.

3B2H6.2NH3 – 2B3N3H6 + 12H2

Additional compound 3B2H6.2NH3 is heated at 200°c then it is given 2B2NH3H6 + 12 H2. (Only hydrogen is remove).

How will convert borane trichloride to inorganic benzene?

It is also prepared with BCl3.

When borane trichloride (3BCl3) is react with ammonia chloride then it is given B3N3H3Cl3. After this, this compound are reduction in sodium brohydride. then it is given B3N3H6 + 3HCl

You know that, it is an aromatic compound because it is obey huckel (4n + 2) π electron rule.

How will you prepared borazine from ammonia?

1. When the B2H6 is react with ( in the excess of ammonia) (NH3) then it is directly given borazine (B3N3H6).

How will you prepared borazine from LiBH4?

2. When 3 LiBH4 + 3NH4Cl, if react then it also give borazine (B3H6N3) and 3LiCl + 9h2.

Difference between Inorganic benzene and benzene?

Here, first we will discuss about inorganic benzene (borazine). after this, we will discuss about benzene.

first off all, you have to draw the structure of inorganic benzene (borazine). because you can understand properly about borazine. we know that Borazine is highly reactive compound. the chemical structure of borazine is more similar to benzene.
