Question

distinguish between dilute kmno4 and cold/hot kmno4​

Answer 1

Answer:

Dihydroxylation of alkenes with cold, dilute KMnO4 to give vicinal diols. Description: Treatment of alkenes with cold, dilute basic KMnO4 leads to 1,2-diols (vicinal diols). Notes: The reaction proceeds with “syn” stereochemistry of the alkene, meaning that the two alcohols end up on the same side of the alkene.

Answer 2

Answer:

• hot acidic KMnO4 is pretty strong oxidizing agent, cold basic KMnO4 is weaker oxidizing agent. Higher concentration means stronger oxidizing agent. It realy depends on what you want to do, but I suppose hot acidic KMnO4 can oxidize and decompose pretty much anything

Hope it helps you !!
