Vedclass · Answer

(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.

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