MCQ
$C{H_3} - C{H_2} - C \equiv CH\mathop {\xrightarrow{R}}\limits_{{H_2}O} $  Butanone, $R$ is
  • $H{g^{ + + }}$
  • B
    $KMn{O_4}$
  • C
    $KCl{O_3}$
  • D
    ${K_2}C{r_2}{O_7}$

Answer

Correct option: A.
$H{g^{ + + }}$
a
(a) It is hydration of alkynes.

$C{H_3} - C{H_2} - C \equiv CH\mathop {\xrightarrow{{H{g^{ +  + }}}}}\limits_{{H_2}O} \mathop {C{H_3} - C{H_2} - \mathop {\mathop C\limits^{||} }\limits^O  - C{H_3}}\limits_{{\text{Butanone}}} $

A trinitro compound, $1, 3,5$ tris-($4$-nitrophenyl) benzene, on complete reaction with an excess of $\mathrm{Sn} / \mathrm{HCl}$ gives major product, which on treatment with an excess of $NaNO_2 /  HCl$ at $0^{\circ} C$ provides $P$ as the product. $P$, upon treatment with excess of $H_2 O$ at room temperature, gives the product $Q$. Bromination of $Q$ in aqueous medium furnishes the product $R$. The compound $P$ upon treatment with an excess of phenol under basic conditions gives the product $S$.

The molar mass difference between compounds $Q$ and $R$ is $474 \mathrm{~mol}^{-1}$ and between compounds $P$ and $S$ is $172.5 \mathrm{~g} \mathrm{~mol}^{-1}$.
