Question

Correct relationship between pairing energy $\left(P\right)$ and C.F.S.E. $\left({\Delta }_0\right)$ in complex ion $\left[Ir\right(H_{2}O{)}_6{]}^{3+}$ isk

• A. ${\Delta }_o<P$
• B. ${\Delta }_o>P$
• C. ${\Delta }_o=P$
• D. Cannot comment

Answer 1

The correct option is A ${\Delta }_o<P$

Water is a weak filed ligand. The crystal field splitting caused by water is small. Hence, ${\Delta }_o<P$.
