$II$ and $IV$

Vedclass · Answer

(C) $CrO_3$ in aqueous $H_2SO_4$ (Jones reagent) is a strong oxidizing agent that oxidizes primary alcohols to carboxylic acids and secondary alcohols to ketones.$(II)$ is a primary diol: $HO-CH_2-CH(CH_3)-CH_2-OH$. Oxidation gives a gem-dicarboxylic acid: $HOOC-CH(CH_3)-COOH$. Gem-dicarboxylic acids readily undergo decarboxylation on heating.$(IV)$ is a secondary-primary diol: $CH_3-CH(OH)-CH_2-CH_2-OH$. Oxidation gives a $\beta$-keto acid: $CH_3-CO-CH_2-COOH$. $\beta$-keto acids readily undergo decarboxylation on heating to form ketones.Thus,$(II)$ and $(IV)$ satisfy the given conditions.

Diols $(I-IV)$ which react with $CrO_3$ in aqueous $H_2SO_4$ and yield products that readily undergo decarboxylation on heating,are
