MCQ
$C{H_3}C{H_2}C \equiv N\xrightarrow{X}C{H_3}C{H_2}CHO$ The compound $X$ is
- ✓$SnCl_2/HCl/H_2O$, boil
- B$H_2/Pd -BaSO_4$
- C$LiAlH_4$/ethe
- D$NaBH_4/ ether / H_3O^+$
$C{{H}_{3}}-C{{H}_{2}}-C\equiv N$ $\xrightarrow{{SnC{l_2}\,/\,HCl}}$ $C{H_3}C{H_2}CH = NH$
$\xrightarrow[{(Ether)}]{{{H_2}O\,,\,boil}}$ $C{H_3}C{H_2}CHO\, + \,N{H_4}Cl$

$\gamma_{1} A +\gamma_{2} B \rightarrow \gamma_{3} C +\gamma_{4} D$
Concentration of $C$ changes from $10\, mmol$ appearance of $D$ is $1.5$ times the rate of disappearance of $B$ which is twice the rate of disappearance $A$. The rate of appearance of $D$ has been experimentally determined to be $9 \,m\,mol$ $dm ^{-3} s ^{-1}$. Therefore the rate of reaction is $......\,m\,mol\, dm ^{-3} \,s ^{-1}$. (Nearest Integer)
