MDCAT Chemistry QUESTION #4345
Question 1
Carboxylic acid reacts with ammonia to form ammonium salts which on heating produces:
  • Carbonates
  • Alkane
  • Ester
  • Amide✔️
Correct Answer Explanation
When a carboxylic acid reacts with $NH_3$, an ammonium salt forms: $RCOOH + NH_3 \rightarrow RCOONH_4$. On heating, water is eliminated and an amide is produced: $RCOONH_4 \xrightarrow{\Delta} RCONH_2 + H_2O$.
