Options
A KMnO4
B MnO2
C K2Cr2O7
D PCC
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

PCC (pyridinium chlorochromate) is a mild oxidizing agent that selectively oxidizes primary alcohols to aldehydes without further oxidation to carboxylic acids. KMnO4 and K2Cr2O7 are strong oxidizing agents that give carboxylic acids.

Hint

Which oxidizing agent is mild and stops at the aldehyde stage?
