Hybridization of chlorine in chlorate ion is sp3 hybridized
and has a pyramidal shape
In chlorate ion ClO3- the three oxygen atom will have 1 unpaired orbital
Chlorine’s unoccupied d orbitals will be used for bonding here. The chlorine
makes 2 double bonds with O and a single bond with O-
One lone pair will be there on chlorines and thus it shows some distortion in the arrangement
1/2{No:of valence electron in central atom+ Monovalent atom attached to central metal atom+anionic charge-cationic charge}
This formula can be used for identifying hybridization or,
(total valence electrons)/8 is used for simple ions
