What is meant by inorganic benzene ? How it is prepared? |
|
Answer» BORAZINE is called inorganic benzene because size of boron and nitrogen atoms RESEMBLES with that of CARBON atoms . Also both rings have aromaticity i.e. have paramagnetic ring current. But the difference arises in polarity. Benzene is non-polar while borazine is polar.Inorganic benzene is B3N3H6. It is also known by the name borazole or borazine. You are already aware with its structure…haven’t u seen the structure of benzene ??..its structure is also like that 3 nitrogen and 3 boron FORMS a ring in which double bond is conjugated (3 double bonds are present) and all six H are attached with every nitrogen and boron.By heating a mixture of LiBH4 and NH4Cl B3N3H6 can be prepared in the laboratory by heating a mixture of LiBH4 and NH4Cl in vaccum at 230 degree celsius. 3NH4Cl + 3LiBH4 B3N3H6 + 3LiCl + 9H2 This method gives 30% Borazine. 230 °C |
