Q80 / 180 · AIIMS 2012 · Chemistry

$\mathrm{PhCH}_2 \mathrm{Cl} \stackrel{\text { aq. NaCN }}{\longrightarrow} ? \stackrel{\text { Catalytic hydrogenation }}{\longrightarrow}$ The final product $(U)$ is :

  • Correct answer
    A
    $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{NH}_2$
  • B
    $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{CONH}_2$
  • C
    $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{NH}_2$
  • D
    $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{NHCH}_3$

Solution

$$ \begin{aligned} & \mathrm{PhCH}_2 \mathrm{Cl} \stackrel{\text { aq. } \mathrm{NaCN}}{\longrightarrow} \mathrm{PhCH}_2 \mathrm{CN} \\ & \stackrel{\text { Cat. hydrogenation }}{\stackrel{\mathrm{H}_2, \mathrm{Pd}}{\longrightarrow}} \mathrm{PhCH}_2 \mathrm{CH}_2 \mathrm{NH}_2 \end{aligned} $$ (U)

Hence, the correct answer is option: 'A'.
