MCQ
Relation between $(A)$ and $(B)$ is

$\begin{array}{*{20}{c}}
  O \\ 
  {||} \\ 
  {C{H_3} - C - N{H_2}} 
\end{array}$ $\xrightarrow{{KOBr}}$ $(A)$

$\begin{array}{*{20}{c}}
  O \\ 
  {||} \\ 
  {C{H_3} - C - N{H_2}} 
\end{array}$ $\xrightarrow{{LiAlH_4}}$ $(B)$

  • A
    Identical
  • B
    Functional isomer
  • Homologous
  • D
    Positional isomers

Answer

Correct option: C.
Homologous
c
$\begin{array}{*{20}{c}}
  O \\ 
  {||} \\ 
  {C{H_3} - C - N{H_2}} 
\end{array}$  $\xrightarrow[{(Hoffmann\,\,broamide)}]{{KOBr}}$ $\mathop {C{H_3} - N{H_2}}\limits_{(A)} $

$\begin{array}{*{20}{c}}
  O \\ 
  {||} \\ 
  {C{H_3} - C - N{H_2}} 
\end{array}$ $\xrightarrow[{(\operatorname{Re} duction)}]{{LiAl{H_4}}}$ $\mathop {C{H_3} - C{H_2} - N{H_2}}\limits_{(B)} $
