Question

Identify $Z$ in the following sequence of reactions.
$\mathrm{CH}{}_3\mathrm{COOH}\stackrel{\mathrm{NH}{}_3}{\to }\mathrm{X}\stackrel{\mathrm{\Delta }}{\to }\mathrm{Y}\stackrel{\mathrm{P}{}_2\mathrm{O}{}_5}{\to }\mathrm{Z}$

• A. $C{H}_4$
• B. $C{H}_{3}CHO$
• C. $C{H}_{3}CN$
• D. $C{H}_{3}CO{O}^{-}N{H}_4^{+}$

Answer 1

Answer: (C)

$\mathrm{CH}{}_3\mathrm{COOH}\stackrel{\mathrm{NH}{}_3}{\to }\underset{{}_{}^{}{}_{}^{\prime }\mathrm{X}{}^{\prime }}{\mathrm{CH}{}_3\mathrm{COONH}{}_4}\underset{\text{-}{\mathrm{H}}_2\mathrm{O}}{\overset{\mathrm{\Delta }}{\to }}\underset{{}_{}^{}{}_{}^{\prime }\mathrm{Y}{}^{\prime }}{\mathrm{CH}{}_3\mathrm{CONH}{}_2}\underset{\text{-}{\mathrm{H}}_2\mathrm{O}}{\overset{{\mathrm{P}}_2{\mathrm{O}}_5}{\to }}\underset{{}_{}^{}{}_{}^{\prime }\mathrm{Z}{}^{\prime }(\mathrm{methyl}\mathrm{cyanide})}{\mathrm{CH}{}_3\mathrm{CN}}$
