Question

The statement(s) true about $PC{l}_{2}B{r}_3$ is/are:

• A. The net dipole moment is zero
• B. $P-Cl$ bonds are longer than $P-Br$ bonds
• C. The hybridization of $P$ is $s{p}^{3}d$
• D. $P-Cl$ bonds are shorter than $P-Br$ bonds

Answer 1

Answer: (A), (C), (D)

The correct options are
A

The net dipole moment is zero

C

The hybridization of $P$ is $s{p}^{3}d$

D

$P-Cl$ bonds are shorter than $P-Br$ bonds

$PC{l}_{2}B{r}_3$ hybridisation- $s{p}^{3}d$
net $\mu =0$
The size of $Cl$ is smaller than the size of $Br$ hence the $P-Cl$ bond is shorter.
