Question

Following conversion can be carried out by using
(1) $ KMn{{O}_{4}} $ in alcohol (2) $ NaClO $ in a buffer (3) $ A{{g}_{2}}O/NaOH,\text{ }HCl $ (4) $ FeC{{l}_{3}} $ in a buffer

• A. 1, 2 and 3 are correct.
• B. 1 and 2 are correct.
• C. 2 and 4 are correct.
• D. 1 and 3 are correct.

Answer 1

Only strong oxidising agents oxidises $ CHO $ group into $ COOH $ group. $ FeC{{l}_{3}} $ in a buffer is not a strong oxidising agent, hence it cannot oxidise $ CHO $ group.
