Question

Identify ' $C$ ' in the following reaction $CH _{3} CH _{2} l \ce{->[{ NaCN }]}A \underset{\text { Partial hydrolysis }}{\ce{->[{ OH ^{-}}]}} B \ce{->[{ Br _{2} / NaOH }]} C$

• A. $CH _{3} CH _{2} NH _{2}$
• B. $CH _{3} CH _{2} CH _{2} NH _{2}$
• C. $CH _{3} NH _{2}$
• D. $CH_{3} CH_{2} - \underset{\overset{||}{O}}{C} - NHBr$

Answer 1

Answer: (A)

$CH _{3} CH _{2} l \ce{->[{ NaCN }]} \underset{(A)}{CH_{3}CH_{2}CN} \ce{->[{OH^{-}}]} \underset{(B)}{CH_{3}CH_{2}CONH_{2}} \ce{->[{Br/NaOH}]} \underset{(C)}{CH_{3}CH_{2}NH_{2}}$
