Vedclass · Answer

(A) spin-free complex,also known as a high-spin complex,is a coordination compound in which the electrons are arranged to maximize the number of unpaired electrons. This occurs when the crystal field splitting energy $(\Delta_o)$ is less than the pairing energy $(P)$,i.e.,$\Delta_o Consequently,the electrons occupy the higher energy orbitals ($e_g$ in octahedral complexes) before pairing in the lower energy orbitals $(t_{2g})$,resulting in a larger total spin value.
