Vedclass · Answer

(A) According to $VSEPR$ theory,the shape of a molecule depends on the number of bonding and non-bonding electron pairs around the central atom.In $BCl_3$,the central $B$ atom has $3$ bonding pairs and $0$ lone pairs,resulting in $sp^2$ hybridization and a trigonal planar geometry.In $NCl_3$,the central $N$ atom has $3$ bonding pairs and $1$ lone pair,resulting in $sp^3$ hybridization and a pyramidal geometry due to the lone pair-bond pair repulsion.
