The relative strength of trichlorides of boron group to accept a pair of electron is given by

A

`GaCl_(3)gtAlCl_(3)gtBCl_(3)`

B

`AlCl_(3)ltBCl_(3)ltGaCl_(3)`

C

`AlCl_(3)ltGaCl_(3)ltBCl_(3)`

D

`BCl_(3)ltAlCl_(3)ltGaCl_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
Lewis acidic strength is in the order
`GaX_(3)ltAlX_(3)ltBX_(3)`
So, acidic strength of trichlorides is as follows:
`GaCl_(3)ltAlCl_(3)ltBCl_(3)`
Hence, strength of accepting electron is as follows: `GaCl_(3)gtAlCl_(3)gtBCl_(3)`
