(d) (CH3)3N​
Plese tell me.

Answer 1

Answer:

Explanation:

Small amines such as NH3, CH3NH2 and (CH3)2 NH give unsymmetrical cleavage of diborane according to following reaction. B2H6 + 2NH3 → [[H2B(NH3)2]+ [BH4]- Large amines, such as (CH3)3 N gives Symmetrical cleavage of diborane according to following reaction. B2H6 + 2 N(CH3)3 → 2H3B ←N (CH3)
