Question

Iodide	$P{I}_3$	$As{I}_3$	$Sb{I}_3$
Bond angle	$102$	$100^{°}{2}^{\prime }$	$99^{°}$

The bond angle is maximum in $P{I}_3$, which is

• A. due to small size of $P$
• B. due to more $bp$- bprepulsion in $P{I}_3$
• C. due to less electronegativity of $P$
• D. None of the above

Answer 1

Answer: (B)

Among $P,As$ and $Sb,P$ is the most electronegative element, due to this, there is more $bp-bp$ repulsion.
