Question

The tendency of BF₃, BCl₃ and BBr₃ to behave as Lewis acid decreases in the sequence:

Moderate

A

BCI₃ < BF₃ < BBr₃
B

BBr₃ > BCI₃ > BF₃
C

BBr₃ < BF₃ < BCI₃
D

BF₃ > BCI₃ >BBr₃

Solution

The effect of increase of $pπ ‐ pπ$ back bonding from BBr₃ to BF_3, hence decreases the Lewis acidic character from BBr₃ to BCl₃ to BF₃.
