Vedclass · Answer

(A) To determine the shape of the given species,we use the $VSEPR$ theory:$1$. $SO_{3}$: The central $S$ atom has $3$ bond pairs and $0$ lone pairs. The geometry is trigonal planar (non-pyramidal).$2$. $NO_{3}^{-}$: The central $N$ atom has $3$ bond pairs and $0$ lone pairs. The geometry is trigonal planar (non-pyramidal).$3$. $PCl_{3}$: The central $P$ atom has $3$ bond pairs and $1$ lone pair. The geometry is trigonal pyramidal.$4$. $CO_{3}^{2-}$: The central $C$ atom has $3$ bond pairs and $0$ lone pairs. The geometry is trigonal planar (non-pyramidal).Thus,the species $SO_{3}$,$NO_{3}^{-}$,and $CO_{3}^{2-}$ are non-pyramidal.The total number of such species is $3$.

The number of species having a non-pyramidal shape among the following is:
$A$. $SO_{3}$
$B$. $NO_{3}^{-}$
$C$. $PCl_{3}$
$D$. $CO_{3}^{2-}$
