In which of the following molecules/ions are all the bonds not equal?

The decreasing order of bond angle in the following molecules is

Identify a pair of molecules having similar shapes of both members.

Match the following molecules/ions in List-$I$ with the number of lone pairs of electrons on the central atom in List-$II$.

List-$I$ (molecule/ion)	List-$II$ (Number of lone pairs of electrons on the central atom)
$(A)$ $XeF_2$	$(I)$ $2$
$(B)$ $XeO_3$	$(II)$ $0$
$(C)$ $XeF_4$	$(III)$ $3$
$(D)$ $PF_6^-$	$(IV)$ $1$

Consider the following reaction:
$2Se_2Cl_2 \to 3Se + SeCl_4$
Choose the $CORRECT$ option regarding the product $SeCl_4$ (referred to as $A$ in the options).

$X$ and $Y$ are two covalent molecules in which the hybridization of the central atoms is the same,but the shapes are different. What are $X$ and $Y$?
