Question

Which of the following alcohols will form an aldehyde or a ketone as a product on oxidation with $H^{+}/K_{2}C{r}_2{O}_7$.

• A. $1^{\circ }$ alcohol
• B. $2^{\circ }$ alcohol
• C. $3^{\circ }$ alcohol
• D. Both $1^{\circ }$ and $2^{\circ }$ alcohol

Answer 1

The correct option is B $2^{\circ }$ alcohol

$2^{\circ }$ alcohol gives ketone under the given conditions and it does not oxidise further.
$1^{\circ }$ alcohol gives an aldehyde which oxidises further to form a carboxylic acid.
$3^{\circ }$ alcohol does not oxidise in such conditions.
