Question

Tertiary alchols $\left(3^o\right)$ having atleast four carbon atoms upon drastic oxidation yield carboxylic acid with:

• A. One carbon atom less
• B. Two carbon atom less
• C. Three carbon atom less
• D. All the above three option are correct

Answer 1

Answer: (A), (B)

The correct options are
A One carbon atom less
B Two carbon atom less

$3^o$ alcohols are resistant to oxidation. under drastic condition. They first form ketone and then acid by loosing one carbon at each step.
$3^o\underset{\left(4C\right)}{alcohol}\underset{\left[o\right]}{\overset{Drasticcondition}{\to }}\underset{\left(3C\right)}{ketone}\underset{}{\overset{\left[o\right]}{\to }}\underset{\left(2C\right)}{acid}$
$\therefore$ Acid having 2C is formed when $3^o$ alcohol is oxidised under drastic conditions.
