Q.
The geometry of $ClO _3^{-}$ion according to Valence Shell Electron Pair Repulsion (VSEPR) theory will be
Chemical Bonding and Molecular Structure
Solution:
According to VSEPR theory, the molecule is of $AB_3E$
type in which arrangement of electron pairs are in tetrahedral shape. But due to a lone pair of electrons, the actual shape is trigonal pyramidal.
