In the following reaction,how do the $Cl-P-Cl$ bond angles change?
$PCl_5 \longrightarrow PCl_4^+ + Cl^-$

Which of the following is planar?

Assertion: The $HOF$ bond angle in $HFO$ is higher than the $HOCl$ bond angle in $HClO$.
Reason: Oxygen is more electronegative than halogens.

State the contribution of Nyholm and Gillespie in $VSEPR$ theory.

The bond angle $H-X-H$ is the greatest in the compound

Given below are two statements:
Statement $(I) :$ For $ClF_3$,all three possible structures may be drawn as follows:
(Image provided)
Statement $(II) :$ Structure $III$ is most stable,as the orbitals having the lone pairs are axial,where the $\ell p-bp$ repulsion is minimum.
In the light of the above statements,choose the most appropriate answer from the options given below:
