Vedclass · Answer

(B) In coordination complexes,the electron distribution is determined by the competition between the crystal field splitting energy $(\Delta_{0})$ and the pairing energy $(P).$If $\Delta_{0} > P$,the energy required to pair electrons is less than the energy required to promote an electron to the higher energy $e_{g}$ orbitals. This leads to the formation of low spin complexes.If $\Delta_{0} Therefore,the condition that favours the formation of high spin complexes is $\Delta_{0} < P$.

The electron distribution in $d^{n}$ coordination complexes depends on the magnitude of crystal field splitting,$(\Delta_{0})$ and pairing energy $(P).$ The condition which favours the formation of high spin complexes is
