$KMnO_4$

Vedclass · Answer

(D) $n$-pentane and isopentane are both alkanes. Isopentane $(CH_3-CH(CH_3)-CH_2-CH_3)$ contains a tertiary hydrogen atom attached to the $C-2$ carbon. Alkanes with a tertiary hydrogen atom can be oxidized by alkaline $KMnO_4$ to the corresponding tertiary alcohol. $n$-pentane $(CH_3-CH_2-CH_2-CH_2-CH_3)$ contains only primary and secondary hydrogen atoms and is resistant to oxidation by $KMnO_4$ under these conditions. Therefore,$KMnO_4$ can be used to distinguish between them.
