Question

$C{H}_{3}COOH\underset{\text{Heat}}{\overset{\mathrm{N}{\mathrm{H}}_3}{\to }}A\underset{(\text{-}{\mathrm{H}}_2\mathrm{O})}{\overset{{\mathrm{P}}_2{\mathrm{O}}_5}{\to }}B\underset{(\text{-}{\mathrm{H}}_2\mathrm{O})}{\overset{{\mathrm{P}}_2{\mathrm{O}}_5}{\to }}C$
The compound ${}^{\prime }{C}^{\prime }$ is:

• A. acetamide
• B. ammonium acetate
• C. methyl cyanide
• D. aniline

Answer 1

Answer: (C)

$\underset{\text{ Acetic acid }}{C{H}_{3}COOH}\underset{\mathrm{\Delta }}{\overset{\mathrm{NH}{}_3}{\to }}\underset{\text{Ammonium acetate}}{\underset{(A)}{C{H}_{3}COON{H}_4}}\underset{\mathrm{\Delta }\text{-}{\mathrm{H}}_2\mathrm{O}}{\overset{{\mathrm{P}}_2{\mathrm{O}}_5}{\to }}\underset{\text{Acetamide}}{\underset{(B)}{C{H}_{3}CON{H}_2}}\underset{{\mathrm{P}}_2{\mathrm{O}}_5/\mathrm{\Delta }}{\overset{+{\mathrm{H}}_2\mathrm{O}}{\to }}\underset{\text{Methyl cyanide}}{\underset{(C)}{C{H}_{3}CN}}$
