Boron and nitrogen form bonds analogous to carbon-carbon bonds. For example, compound ammonia borane, NH ₃- BH ₃ , contains B - N bond analogous to the C - C bond in ethane. Borazine ( B ₃ ~N ₃ H ₆ ) is analogous to benzene and is prepared by reacting NH ₄ Cl with BCl ₃ followed by reduction using LiBH ₄ . The correct statement(s) is/are
Options
- ABoron nitride (BN) has a structure similar to graphite and is a good conductor of electricity.
- BThe B-center in borazine is susceptible to nucleophilic attack.
- CEthane is a gas at room temperature, while ammonia borane is not so.
- DThe reaction of HCl with borazine gives hexachloro derivative of borazine.
Correct answer
C. Ethane is a gas at room temperature, while ammonia borane is not so.
