In the following reaction. 2X + B(2)H(...

In the following reaction.
`2X + B_(2)H_(6) rarr [BH_(2)(X)_(2)]^(oplus) [BH_(4)]^(Ө)`
The amine `(s) x` is /are.

A

`NH_(3)`

B

`CH_(3)NH_(2)`

C

`(CH_(3))_(2)NH`

D

`(CH_(3))_(3)N`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Small amines, such as `NH_(3),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) to [H_(2)B(NH_(3))_(2)]^(+)[BH_(4)]^(-)`
Large amines, such as `(CH_(3))_(3) N`, give symmetrical cleavage of diborane according to following reaction :
`B_(2)H_(6)+2N(CH_(3))_(3) to 2H_(3)B larr N(CH_(3))_(3)`
