Question

Identify Z in the sequence $C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }X\xrightarrow[\Delta ]{{{P}_{2}}{{O}_{5}}}Y\xrightarrow{{{H}_{2}}O/{{H}^{+}}}Z$

• A. $C{{H}_{3}}C{{H}_{2}}CON{{H}_{2}}$
• B. $C{{H}_{3}}CN$
• C. $C{{H}_{3}}COOH$
• D. ${{(C{{H}_{3}}CO)}_{2}}O$

Answer 1

Answer: (C)

$C{{H}_{3}}COOH$

Answer 2

$C{{H}_{3}}COON{{H}_{4}}\xrightarrow{\Delta }\underset{\begin{smallmatrix} \text{acetamide} \\\ \,\,\,\,\,\,\,\,(X) \end{smallmatrix}}{\mathop{C{{H}_{3}}CON{{H}_{2}}}}\,$ $\underset{(-{{H}_{2}}O)}{\mathop{\xrightarrow[\Delta ]{{{P}_{2}}{{O}_{5}}}}}\,\underset{\text{(Y)}}{\mathop{\underset{\text{methyl}\,\text{cyanide}}{\mathop{\text{C}{{\text{H}}_{\text{3}}}\text{CN}}}\,}}\,\xrightarrow{{{H}_{2}}O/{{H}^{+}}}\underset{(Z)}{\mathop{\underset{acetic\,acid}{\mathop{C{{H}_{3}}COOH}}\,}}\,$
