Above conversion can be achieved by

  • A
    $KMnO_4, \Delta$ followed by $H^+$
  • $I_2/NaOH$ followed by $H^+$
  • C
    $H_2/Pt$
  • D
    $LiAlH_4$

Answer

Correct option: B.
$I_2/NaOH$ followed by $H^+$
b
Iodoform test.

$(a)$ Oxidative ozonolysis by not $KMnO_4$

$(b)$ Iodoform test. Only methyl ketones. No reaction with double bond.

$(c)\, H_2/Pt$ can reduce only double bond.

$(d)\, LAH$ oxidizes ketone to $2^o$ alcohol not to carboxylic acid.
