Question

Which of the following are the incorrect conversion of acetone into acetamide?

• A. $CH _{3} COCH _{3} \xrightarrow{ Pd / BaSO _{4}} CH _{3} CHO \xrightarrow{ NH _{3}}CH _{3} CH _{2} NH _{2}\xrightarrow{ H _{2} O } CH _{3} CONH _{2}$
• B.
• C. $CH _{3} COCH _{3} \xrightarrow{ CrO _{3}} CH _{3} COOH \xrightarrow{ NH _{3}}CH _{3} CONH _{2}$
• D. $CH _{3} COCH _{3} \xrightarrow{ I _{2} / NaOH }CH _{3} COOH \xrightarrow{ HCl }CH _{3} COCl \xrightarrow{ NH _{3}} CH _{3} CONH _{2}$

Answer 1

Answer: (A), (C), (D)

$a, c, d$ are incorrect. Only (b) is correct, i.e.
$\underset{\text { Acetone }}{ CH _{3} COCH _{3}} \xrightarrow{ I _{2} / NaOH }\underset{\text { Sodium acetate }}{ CH _{3} COONa } \xrightarrow[ NH _{3}]{ H ^{+}}$
$\underset{\text{Acetamide}}{CH _{3} CONH _{2}} \xleftarrow{\Delta} \underset{\text{Ammonium acetate}}{CH _{3} CO\overset{-}{O}\overset{+}{N}H _{4}}$
