Question

State True or False.

The bond angle around B in $BC{l}_3$ and $B{F}_3$ is same.

• A. True
• B. False

Answer 1

The correct option is B False

The given statement is False.
The bond angle around B in $BC{l}_3$ is higher than the bond angle around B in $B{F}_3$. F is more electronegative than Cl. Hence, the bond pair of electrons of $B-F$ bond are more towards F and away from B whereas the bond pair of electrons of $B-Cl$ bond are away Cl and more towards B. closer are the bond pair of electrons towards B, greater is interelectronic repulsion and greater is the bond angle.
