Which of the of the following fluoro -compouds is most likely to beahve as a Lewis base?

A

`BF_(3)`

B

`PF_(3)`

C

`CF_(4)`

D

`SiF_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Key Idea - The molecule with lone pair at centre atom, will behave as Lewis base. In the given molecules, only `PF_(3)` has lone pair at P as shown below :

Thus, `PH_(3)` acts as a Lewis base (electron-pair donor) due to presence of lone pair on P-atom.
