Correct option: (a) x > y > z
Explanation:
Therefore, repulsion between both C – O bonds will be greater than the repulsion between C – H bond and C – OH bond or between C – H and C = O bond. Repulsion between C – H and C = O bond is greater than that of between C – H and C – OH bond, because double bond character in C – OH bond will always be less than C = O.
