Question

Identify $$X$$ and $$Y$$ in the reaction.
\[C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\, \end{smallmatrix}}{\mathop{-CH-}}\,CON{{H}_{2}}\xrightarrow{\frac{B{{r}_{2}}}{NaOH}}\]     \[X\xrightarrow{HN{{O}_{2}}}Y\]

A. \[X=C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\,\, \end{smallmatrix}}{\mathop{-CH-}}\,C{{H}_{2}}N{{H}_{2}};\]      \[Y=C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\,\, \end{smallmatrix}}{\mathop{-CH-}}\,C{{H}_{2}}-OH\]
B. $$X = C{H_3}CH = CHN{H_2};$$     $$Y = C{H_3}CH = CHOH$$
C. \[X=C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\,\, \end{smallmatrix}}{\mathop{-CH-}}\,N{{H}_{2}};\]     \[Y=C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\,\, \end{smallmatrix}}{\mathop{-CH-}}\,OH\]  
D. $$X = C{H_3}C{H_2}C{H_2}N{H_2};$$     $$Y = C{H_3}C{H_2}C{H_2}OH$$
Answer :   \[X=C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\,\, \end{smallmatrix}}{\mathop{-CH-}}\,N{{H}_{2}};\]     \[Y=C{{H}_{3}}\underset{\begin{smallmatrix} |\,\,\,\,\, \\ C{{H}_{3}}\,\, \end{smallmatrix}}{\mathop{-CH-}}\,OH\]
