Which of the following has the minimum heat of dissociation?

A

`[(CH_(3))_(3)NtoBF_(3)]`

B

`[(CH_(3))_(3)NtoB(CH_(3))F_(2)]`

C

`[(CH_(3))_(3)NtoB(CH_(3))_(2)F]`

D

`[(CH_(3))_(3)NtoBF_(3)]`

Text Solution

Verified by Experts

The correct Answer is:
D
The tendency of trimethyl boron to act as Lewis acid decreases due to `+IE` of `CH_(3)` group and thus, coordination becomes weaker.
