Vedclass · Answer

(A) The reaction of an alkene with hot acidic $KMnO_4$ causes oxidative cleavage of the double bond.An alkene of the form $R_2C=CH-R'$ will be cleaved to form a ketone $(R_2C=O)$ and a carboxylic acid $(R'-COOH)$.The products given are butan$-2-$one $(CH_3-CH_2-CO-CH_3)$ and pentanoic acid $(CH_3-CH_2-CH_2-CH_2-COOH)$.Combining these fragments at the carbonyl carbons,the original alkene must be $3-$methylhept$-2-$ene $(CH_3-CH_2-C(CH_3)=CH-CH_2-CH_2-CH_3)$.
