MCQ
$C{H_3}CH = CHCHO$ is oxidised to $C{H_3}CH = CHCOOH$ using
  • A
    Alkaline $KMn{O_4}$
  • B
    Selenium dioxide
  • ✓
    Ammoniacal $AgN{O_3}$
  • D
    All of these
✓

Answer

Correct option: C.
Ammoniacal $AgN{O_3}$
c
(c)$C{H_3}CH = CHCHO + 2{[Ag{(N{H_3})_2}]^ + } \to $

$2Ag + 4N{H_3} + C{H_3}CH = CHCOOH + {H_2}O$
