The compound formed when 2- butenes is treated with hot alkaline KMnO_(4) is :

Alkenes undergo a variety of oxidation reactions. With cold and neutral or alkaline KMnO_(4) , alkenes are oxidised to give vicinal diols. Oxidation with hot KMnO_(4) undergoes cleavage of C=C bond leading to the formation of carboxylic acids, ketones and carbon dioxide depending on the nature ofalkene. Reductive ozonolysis of alkenes give aldehydes or ketones. 2-Methyl propene on treatment with hot alkaline KMnO_(4) gives

Butyne-1 on oxidation with hot alkaline KMnO_4 would give
