Which of the following statements is correct for diborane?

Options

A. Small amines like `NH_(3), CH_(3)NH_(2)` give unsymmetrical cleavage of diborane.
B. Large amines such as `(CH_(3))_(3)N` and pyridine gives symmetrical cleavage of diborane.
C. Small as well as large amines both gives symmetrical cleavage of diborane.
D. (A) and (B) both

Answer

D

Explanation

`B_(2)H_(6)+2NH_(3)to [H_(2)B(NH_(3))_(2)]^(+)+[BN_(4)]^(-)`
`B_(2)H_(6)+2N(CH_(3))_(3)to2H_(3)B larrN(CH_(3))_(3)`
