Q. Tertiary alcohols (3${^\circ}$) having at least four carbon atoms upon drastic oxidation yield carboxylic acid with
A) One carbon atom less
B) Two carbon atoms less
C) Three carbon atoms less
D) All the above three options are correct
Explanation
(b)
$3{^\circ}$alcohols are resistant to oxidation under drastic condition. They first form ketone and then acid by loosing one carbon at each step.
$3{^\circ}$ alcohol $\underset{\lbrack O\rbrack}{\overset{Drastic\ condition}{\rightarrow}}\ \ \$ketone $\overset{\ \ \lbrack O\rbrack\ \ \ }{\rightarrow}acid$
(4C) (3C) (2C)
$\therefore$Acid having 2C is formed when $3{^\circ}$ alcohol is oxidised under drastic conditions.
