Vedclass · Answer

(C) The reaction of an alkene with dilute aqueous $KMnO_4$ (Baeyer's reagent) at room temperature is a syn-hydroxylation reaction.$R-CH=CH-R \xrightarrow[	ext{room temp.}]{	ext{dil. aqueous } KMnO_4} R-CH(OH)-CH(OH)-R$ (vicinal diol).In contrast,concentrated $KMnO_4$ with heat causes oxidative cleavage of the double bond to form carboxylic acids.

Dilute aqueous $KMnO_4$ at room temperature reacts with $R-CH=CH-R$ to give:
