Suggest a suitable oxidising reagent for the following conversions:

A

a.`MnO_(2)` in `(A)` and `CrO_(3)` (in glacial acetic acid) in `(B)`.

B

b.`CrO_(3)` in (A) and `MnO_(2)` in `(B)`.

C

c.Both are correct

D

d.Both are incorrect

Text Solution

Verified by Experts

The correct Answer is:
A
In `(A)` the oxidation of allylic `1^(@)` alcohol to aldehyde is carried out with `MnO_(2)`, while in `(B)` the oxidation of `2^(@)` alcohol to ketone is carried out with `CrO_(3) + CH_(3)COOH`. So the answer is `(a)`.
