Vedclass · Answer

(D) In $POCl_3$,the central $P$ atom is bonded to one $O$ atom via a double bond and three $Cl$ atoms via single bonds. $1$. The Lewis structure of $POCl_3$ follows the octet rule for all atoms (including $P$ which expands its octet to $10$ electrons),so it does not violate the octet rule in the context of hypervalency. $2$. The geometry is irregular tetrahedral due to the presence of different types of bonds ($P=O$ and $P-Cl$). $3$. According to $VSEPR$ theory,the repulsion between a double bond $(P=O)$ and a single bond $(P-Cl)$ is greater than the repulsion between two single bonds ($P-Cl$ and $P-Cl$). $4$. Due to the greater repulsion from the $P=O$ bond,the $Cl-P=O$ bond angle ($109.5^{\circ}$ approximately) is actually greater than the $Cl-P-Cl$ bond angle $(103.5^{\circ})$. Therefore,the statement in option $D$ is incorrect.

Which of the following is not correct regarding the structure of $POCl_3$?
