Question: A and B in the following reactions are $ R-\underset{\underset{O}{\mathop{||}}}{\mathop{C}}-{R}’\underset{KCN}{\mathop{\xrightarrow{HCN}}}A\xrightarrow{B}\begin{matrix} R \\ R \\ \end{matrix}>C<\begin{matrix} OH \\ CH_2NH_2 \\ \end{matrix} $
[CBSE PMT 2003]
Options:
A) $ A=RR’C<\begin{matrix} CN \\ OH \\ \end{matrix},B-LiAlH_4 $
B) $ A=RR’C<\begin{matrix} OH \\ COOH \\ \end{matrix} ,B-NH_3 $
C) $ A=RR’C<\begin{matrix} CN \\ OH \\ \end{matrix}\ ,B=H_3{O^{\oplus }} $
D) $ A=RR’CH_2CN,B=NaOH $
Show Answer
Answer:
Correct Answer: A
Solution:
$ R-CO-R’\xrightarrow{HCN}R-\underset{\text{(}A\text{)}}{\mathop{\underset{_CN^{|}}{\overset{ _{|}^{OH}}{\mathop{C-R’}}}}}\xrightarrow{LiAlH_4} $
$ R-\underset{ _{R’}^{|}}{\overset{ _{|}^{OH}}{\mathop{C-CH_2NH_2}}} $
