Question

Find the number of molecules(s) among the following which is/are planar and have dipole moment.
$S{F}_4,PC{l}_3{F}_2,PC{l}_2{F}_3,{I_3}^{-},Br{F}_3,{IC{l}_2}^{-},Xe{F}_4$

Answer 1

The number of molecules(s) which is/are planar and having dipole moment is 1.
$S{F}_4$ has irregular tetrahedral geometry. it is non-planar and has dipole moment.
$PC{l}_3{F}_2$ has trigonal bipyramidal geometry. it is non-planar and has zero dipole moment.
$PC{l}_2{F}_3$ has trigonal bipyramidal geometry. it is non-planar and has dipole moment.
$I_3^{-}$ is linear and has zero dipole moment.
$Br{F}_3$ is T shaped molecule. It is planar and has a dipole moment.
$IC{l}_2^{-}$ is linear and has zero dipole moment.
$Xe{F}_4$ has square planar geometry and has zero dipole moment.
