Choose the comound which can react with [Ag(NH_(3)))(2)]^(+) and on treatment with alkaline KMnO_(4) gives (CH_(3))_(3)C-O OH

Ortho chlorotoluene on oxidation with KMnO_(4) gives :

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. But-2-ene on treatment with cold alk. KMnO_(4) gives
