Vedclass · Answer

(D) Tertiary alcohols $(3^{\circ})$ are resistant to oxidation under mild conditions. However,under drastic conditions (e.g.,using concentrated $HNO_3$ or $KMnO_4$ at high temperatures),they undergo carbon-carbon bond cleavage.First,the tertiary alcohol is oxidized to a ketone by losing one carbon atom.Then,the resulting ketone undergoes further oxidation,which involves the cleavage of the carbon-carbon bond,resulting in the loss of more carbon atoms to form carboxylic acids.Specifically,for a tertiary alcohol with $n$ carbon atoms,the oxidation process involves the loss of carbon atoms at each step of the cleavage,leading to products with fewer carbon atoms than the parent alcohol. The reaction follows the general pathway: $R_3C-OH$ $\xrightarrow{[O]} R_2C=O$ $\xrightarrow{[O]} R-COOH$.Thus,the resulting carboxylic acid has fewer carbon atoms than the original tertiary alcohol.

Tertiary alcohols $(3^{\circ})$ having at least four carbon atoms upon drastic oxidation yield carboxylic acid with:
