What are the number of bond pairs and the number of lone pair electrons in $OF_2$,respectively?

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)
$(A)$ $XeF_2$	$(I)$ $2$
$(B)$ $XeO_3$	$(II)$ $0$
$(C)$ $XeF_4$	$(III)$ $3$
$(D)$ $PF_6^-$	$(IV)$ $1$

Which species is planar?

The correct order of bond angles (smallest first) in $H_2S, NH_3, BF_3$ and $SiH_4$ is

$XeF_2$ molecule is

$A$ molecule $XY_2$ contains two $\sigma$,two $\pi$-bonds and one lone pair of electron in the valence shell of $X$. The arrangement of lone pair as bond pair is
