  • question_answer \[C{{H}_{3}}C{{H}_{2}}Br\xrightarrow[\Delta ]{aq.\,\,KOH}A\xrightarrow[\Delta ]{KMn{{O}_{4}}/{{H}^{+}}}\] \[B\xrightarrow[\Delta ]{N{{H}_{3}}}C\xrightarrow[alkali]{B{{r}_{2}}}D,\,\,D\] is

    A)  \[C{{H}_{3}}Br\]

    B)  \[C{{H}_{3}}CON{{H}_{2}}\]

    C)  \[C{{H}_{3}}N{{H}_{2}}\]

    D)  \[CHB{{r}_{3}}\]

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}C{{H}_{2}}Br\xrightarrow[\Delta ]{aq.\,\,KOH}\underset{(A)}{\mathop{C{{H}_{3}}C{{H}_{2}}OH}}\,\xrightarrow[\Delta ]{KMn{{O}_{2}}/{{H}^{+}}}\]                           \[\underset{\begin{smallmatrix}  acetic\text{ }acid \\  (B) \end{smallmatrix}}{\mathop{C{{H}_{3}}COOH}}\,\xrightarrow{N{{H}_{3}}}C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }\underset{\begin{smallmatrix}  acetamide \\  (C) \end{smallmatrix}}{\mathop{C{{H}_{3}}CON{{H}_{2}}}}\,\]           \[\xrightarrow{B{{r}_{2}}/Alkali}\underset{\begin{smallmatrix}  methyl\text{ }amine \\  (D) \end{smallmatrix}}{\mathop{C{{H}_{3}}N{{H}_{2}}}}\,\]
