Write the s

Answer :

Electronic configuration of Co: [Ar]3d74s2

Electronic configuration of Co3+ : [Ar]3d64s0

Since NH3 is a weak field ligand no pairing up of electrons occurs. Hence forms a high spin complex.

Since there are 6 ligands the hybridization will be sp3d2 as the inner d-orbitals are not vacant.

Shape of sp3d2 will be octahedral.

IUPAC name: Hexaamminecobalt(III)ion
