Question:
A, B and C respectively are
A, B and C respectively are
Updated On: Apr 1, 2025
- ethanol, ethane nitrile and ethyne
- ethane nitrile, ethanol and ethyne
- ethyne, ethanol and ethane nitrile
- ethyne, ethane nitrile and ethanol
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Let's analyze the reactions step by step:
- A to B: The compound A undergoes acidic hydration (HgSO4/H2SO4) which leads to the formation of ethanol (CH3CH2OH), as it is a common reaction to convert alkenes (ethyne, in this case) to alcohols.
- B to C: The reaction of ethanol with PCC (Pyridinium chlorochromate) is an oxidation reaction, converting ethanol (CH3CH2OH) into ethane nitrile (CH3CN).
- C to Acetaldehyde: Ethyne (C2H2) undergoes hydrolysis under SnCl2/HCl followed by acid treatment to produce acetaldehyde (CH3CHO).
The correct answer is (C) : ethyne, ethanol and ethane nitrile.
