$CH_3-CH=CH-CH_2-CH_3$

Vedclass · Answer

(C) The correct answer is $C$. $CH_3-CH=CH-CH_2-CH_3$ is an alkene (pent$-2-$ene). Alkenes contain a carbon-carbon double bond,which undergoes oxidation with cold dilute alkaline $KMnO_4$ (Baeyer's reagent) to form vicinal diols,resulting in the decolourization of the purple $KMnO_4$ solution. Option $A$ is an alkane,option $B$ is naphthalene (an aromatic hydrocarbon),and option $D$ is an alkane,none of which react with cold dilute $KMnO_4$ under standard conditions.
