Question

Iodide	$PI_3$	$AsI_3$	$SbI_3$
Bond angle	$102$	$100^°2'$	$99^°$

The bond angle is maximum in $PI_3$, which is

• A. due to small size of $P$
• B. due to more $bp$- bprepulsion in $PI_3$
• 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 $b p-b p$ repulsion.
