Consider the following statements, I and II:I : $\left[\mathrm{Rh}(\mathrm{CO})_{2} \mathrm{I}_{2}\right]^{-}$ catalytically converts $\mathrm{CH}_{3} \mathrm{I}$ and CO to $\mathrm{CH}_{3} \mathrm{COI}$II : $\left[\mathrm{Rh}(\mathrm{CO})_{2} \mathrm{I}_{2}\right]^{-}$ is diamagnetic in natureThe correct from the following is
(a)I and II are correct and II is an explanation of I
(b)I and II are correct and II is not an explanation of I
(c)I is correct and II is incorrect
(d)I and II are incorrect
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
[Rh(CO)₂I₂]⁻ is the Monsanto acetic-acid catalyst (I true) and, as a d⁸ square-planar complex, is diamagnetic (II true); its diamagnetism is not the reason for its catalysis.
