(D) In $BrF_5$,the central atom $Br$ has $7$ valence electrons. $5$ electrons form bonds with $5$ $F$ atoms,leaving $2$ electrons ($1$ lone pair). In $XeO_3$,$Xe$ has $8$ valence electrons. $6$ electrons form double bonds with $3$ $O$ atoms,leaving $2$ electrons ($1$ lone pair). In $SO_2$,$S$ has $6$ valence electrons. $4$ electrons form double bonds with $2$ $O$ atoms,leaving $2$ electrons ($1$ lone pair). Thus,the number of lone pairs are $1, 1, 1$ respectively.

List-$I$ Molecule/ion	List-$II$ Bond pair : lone pair (on the central atom)
$A. ICl_2^-$	$I. 4 : 2$
$B. H_2O$	$II. 4 : 1$
$C. SO_2$	$III. 2 : 3$
$D. XeF_4$	$IV. 2 : 2$

The number of lone pairs of electrons on the central atom of $BrF_5, XeO_3, SO_2$ respectively are
