Which ONE of the following statements is CORRECT? Methanol carbonylation is faster and more effective using Rh(l) is faster than Ir(l) Rh-based catalysts because oxidative addition to O Methanol carbonylation is faster and more effective using Ir-based catalysts because oxidative addition to Ir(1) is faster than Rh(l) Methanol carbonylation does not involve migratory insertion Methanol carbonylation does not involve reductive elimination

Explanation / Answer

In methanol carbonylation,there are both oxidative addition and migratory insertion steps are present.So last two option are incorrect.In methanol carbonylation,the rate determining step is the oxidative addition step.And since oxidative addition of Ir(I) is faster than that of the Rh (I) and also cost of Ir-based catalyst is less than that of Rh-based catalyst,so 2nd option is the correct option among these.
