Which of these is least likely to act as Lewis base?

A

`F^(-)`

B

`BF_(3)`

C

`PF_(3)`

D

`CO`

Text Solution

Verified by Experts

The correct Answer is:
B
`BF_(3)` cannot act as a Lewis base because its central atom, boron, is electron defient. It is a typical I Lewis acid. If possible, it can donate the lone pair only through its F atoms.
