In the reaction
`2x+B_(2)H_(6)to [BH_(2)(x)_(2)]^(+)[BH_(4)]^(-)`
The reagents (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)+2NH_(3)rarr[H_(2)B(NH_(3))_(2)]^(+)[BH_(4)]^(-)`
Large amines, such as `(CH_(3))_(3)N` gives symmetrical cleavage of diborane according to following reaction
`B_(2)H_(6)+2N(CH_(3))_(3)_(3)`rarr2H_(3)BrarrN(CH_(3))_(3)`
