AIIMS 2014 Chemistry Oxidation Reactions MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Butyne-1 on oxidation with hot alkaline KMnO4 would give
A
CH3CH2CH2COOH
B
CH3CH2COOH
C
CH3CH2COOH + CO2 + H2O
D
CH3CH2COOH + HCOOH
Correct Answer
Option D
Detailed Explanation
The correct answer is D) CH3CH2COOH + HCOOH because the oxidation of butyne-1 (an alkyne) with hot alkaline KMnO4 leads to a cleavage reaction, resulting in the formation of acetic acid (CH3CH2COOH) and formic acid (HCOOH). The strong oxidizing conditions break the triple bond and oxidize the terminal carbon, producing these two carboxylic acids as products.
