Which of the following halides is the most acidic?

A

`PCl_(3)`

B

`SbCl_(3)`

C

`BiCl_(3)`

D

`C Cl_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`C Cl_(4)` cannot accept a lone pair of electron. As such it is not a Lewis acid. Acid strength of trichlorides is in the order
`PCl_(3) gt AsCl_(3) gt SbCl_(3)`
Thus `PCl_(3)` is more acidic than `SbCl_(3)`.
