Consider the following transformation, reactions in the context of co-enzyme $\mathrm{B_{12}}$

(A) 1, 2-Carbon shift

(B) Hydration of $\mathrm{CO_2}$

(D) dimethyl sulfide to demethyl sulfoxide

The correct statement(s) for co-enzyme $\mathrm{B_{12}}$ is/are

(a)A, C, D

(b)A, B only

(c)B, C only

(d)A only

Answer

Answer: D ✓ checked by 4AB · confidence medium

Explanation

Coenzyme B₁₂ enzymes catalyse radical 1,2-carbon-skeleton shifts; CO₂ hydration (Zn), arene hydroxylation and sulfoxidation are not B₁₂ chemistry — A only.
