What is the number of bond pair of electrons and lone pair of electrons present in the valence shell of chalcogens in their hydrides $(H_2X)$?

Given below are two statements:
Statement $I$: The number of compounds among $SO_2$, $SO_3$, $SF_4$, $SF_6$ and $H_2S$ in which sulphur does not obey the Octet rule is $3$.
Statement $II$: Among $[H_2O, ClF_3, SF_4]$, $[NH_3, BrF_5, SF_4]$, $[BrF_5, ClF_3, XeF_4]$ and $[XeF_4, ClF_3, H_2O]$, the number of sets in which all the molecules have one lone pair of electrons on the central atom is $1$.

Which of the following molecules is linear?

Match the following:

List-$I$	List-$II$
$a$. See-Saw Shape	$i$. $XeF_4$
$b$. Square Pyramidal	$ii$. $ClF_3$
$c$. $T$-Shape	$iii$. $PbCl_2$
$d$. Bent Shape	$iv$. $SF_4$
	$v$. $BrF_5$

The correct answer is

Identify the correct statement regarding geometry and lone pair of electrons present in $CH_4$ and $SiCl_4$.

Bond angles $104^o$,$117^o$ and $180^o$ are associated with
