Does alcohol react with potassium permanganate?

Does alcohol react with potassium permanganate?

Potassium permanganate (KMnO4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. KMnO4 will readily react with a carbon-carbon double bond before oxidizing a primary alcohol.

Is potassium permanganate soluble in methanol?

Potassium permanganate is soluble in acetone, water, pyridine, methanol and acetic acid. It is also readily soluble in inorganic solvents.

Does KMnO4 test for alcohol?

A potassium permanganate (KMnO4) solution is a test for unsaturation (alkenes and alkynes) or functional groups that can be oxidized (aldehydes and some alcohols, Figure 6.66). The permanganate ion (MnO−4) is a deep purple color, and upon reduction converts to a brown precipitate (MnO2).
