Kaplan has two reactions with KMnO4

A) 1. KMnO4, OH-, heat / 2. H+

B) cold, dilute KMnO4

What is the mechanism of each of these reactions??

ok my friend, the cold Kmno4 undergoes a dihydroxylation reaction
and hot kmno4 give u carboxylic acid.

hot kmno4 gives u COOH if it's primary OH.
secondary OH becomes ketone.
