The formula of inorganic benzene is (BH)3(NH)3
Formula of Inorganic Benzene
Inorganic benzene is also known as borazine which is an inorganic and a cyclic compound. There are three BH units and three NH units alternate. The chemical formula of inorganic benzene is:
Inorganic Benzene Structure
Why is borazine called ‘inorganic benzene’?
Borazine is called ‘inorganic benzene’ because the compound is isoelectronic and isostructural with benzene. The other similarities are it is a colourless liquid with aromatic smell. Borazine is said to be aromatic because the number of pi electrons obeys 4n+2 rule and the B-N bond lengths are all equal.
Preparation of Inorganic Benzene
There are three different ways to prepare inorganic benzene and they are:
- Stock and Pohlands method:
The yield obtained by this method is low because there is a simultaneous formation of solid polymeric by-products.
- Heating BCl3 with NH4Cl:
- By heating mixture of LiBH4 and NH4Cl:
This method gives up to 30% Borazine.
