JEE Main Chemistry question

Statement 1 (Assertion): Boranes are volatile and decompose into boron and hydrogen at red heat. Statement 2 (Reason): All the boranes react with ammonia depending on the conditions.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for AssertionCorrect
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (B)

Solution

Boranes are indeed volatile compounds, and on strong heating (red heat) they decompose, ultimately giving elemental boron and hydrogen (via a series of higher boranes), so the assertion is true. Separately, it is also true that boranes react with ammonia under varying
