In the reaction, $2 X + B_{2} H_{6} ⟶ [BH_{2} (X)_{2}]^{+} [BH_{4}]^{-}$ The amine (s) $X$ , is (are)

Options:(select one or more)

Answer:

B, C

Solution:

Small amines such as $NH_{3} \cdot CH_{3} NH_{2}$ and $(CH_{3})_{2} NH$ give unsymmetrical cleavage of diborane according to following reaction, $B_{2} H_{6} + 2 NH_{3} ⟶ [H_{2} B (NH_{3})_{2}]^{+} [BH_{4}]^{-}$ Large amines, such as $(CH_{3})_{3} N$ give symmetrical cleavage of diborane.
