Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Question Explanation:

The question asks which given alcohols can undergo oxidation in the presence of potassium chromate

(K₂CrO₄ ), which selectively oxidises certain types of alcohols.

Concept:

This question is based on Oxidation of Alcohols.

Solution:

K₂CrO₄ (in acidic medium) oxidises primary alcohols to acids and secondary alcohols to ketones, but

does not oxidise tertiary alcohols due to absence of α‑hydrogen.

CH₃CH₂OH → CH₃COOH

(CH₃)2CHOH→(CH₃)₂CO

Allyl alcohol is a primary alcohol and is oxidised, while tert‑butyl alcohol is tertiary and resists

oxidation. Final Answer: Option (A, C & D)
