I got this question in an online interview.

This interesting question is from p-Block Elements topic in section p-Block Elements of Chemistry – Class 11

Answer 1

Correct option is (b) 1:2

Explanation: Borazine is prepared from diborane. When 3 moles of diborane combines with 6 moles of ammonia on heating, it gives two moles of inorganic benzene and 12 moles of hydrogen molecules, that means we need diborane and Ammonia in the ratio 1:2.
