MHT CET 2024 Chemistry question
Identify the product obtained when alkenes react with cold and dilute alkaline potassium permanganate ?
Answer: (B)
Solution
Cold, dilute, alkaline (Baeyer's reagent) hydroxylates the C=C bond by syn addition of two OH groups, giving a vicinal diol (a glycol), e.g. CH_2=CH_2 \to HOCH_2CH_2OH; the purple colour of permanganate is discharged (Baeyer's test for unsaturation).
