Product  $ X$ is

  • A
    $C{H_3}C{H_2}C{H_2}CH(OH)C{H_3}$
  • ✓
    $C{H_3}CH = CHCOC{H_3}$
  • C
    Both $(a)$ and $(b)$ are correct
  • D
    $C{H_3}C{H_2}C{H_2}COC{H_3}$
✓

Answer

Correct option: B.
$C{H_3}CH = CHCOC{H_3}$
b
The Jones Reagent is a solution of chromium trioxide in diluted sulfuric acid that can be used safely for oxidations of organic substrates in acetone. It is used for the oxidation of primary and secondary alcohols to carboxylic acids and ketones, respectively.

The given compound is a secondary alcohol, hence, it will give a ketone.
