Trigonal planar

Vedclass · Answer

(A) In a trigonal bipyramidal electron geometry,the central atom has $5$ electron pairs. According to $VSEPR$ theory,lone pairs occupy equatorial positions to minimize repulsion. Possible molecular geometries derived from this include: $1$. $4$ bonding pairs + $1$ lone pair = See-saw $2$. $3$ bonding pairs + $2$ lone pairs = $T$-shaped $3$. $2$ bonding pairs + $3$ lone pairs = Linear Trigonal planar geometry arises from a trigonal planar electron geometry ($3$ electron pairs). Therefore,trigonal planar is the least likely geometry to result from a trigonal bipyramidal electron geometry.
