Question

Weak field ligands form high spin complexes due to (where $\Delta_{0}$ is crystal field splitting and $P$ = pairing energy)

• A. $\Delta_{0}>P$
• B. $\Delta _{0} < P$
• C. $\Delta _{0}=P$
• D. $\Delta _{0}=0$

Answer 1

Answer: (B)

$\Delta _{0} < P$

Answer 2

Weak field ligands form high spin complexes due to $\Delta_{0}< p$.
where, $\Delta_{0}=$ crystal field splitting $P =$ pairing energy
