Asked in FBISE Chemistry 2022 SLO — Paper 3 2022

Identify the name of the compound which will give acetamide on heating?

Correct answer: D. Ammonium Acetate

  • A. Ethyl amine
  • B. Ethyl Nitrile
  • C. Ethyl Diazonium Chloride
  • D. Ammonium Acetate

Explanation

Carboxylic acids react with ammonia to form ammonium salts which on heating produce acid amides. CH3COOH + NH3 → CH3COONH4+ → CH3CONH2 + H2O (HEAT)

About Carboxylic Acid Derivatives

Carboxylic acid derivatives include acid halides, acid anhydrides, esters and amides, formed by replacing the hydroxyl group of a carboxylic acid. Their nomenclature, structures, preparation, hydrolysis and relative reactivity are linked through nucleophilic acyl substitution, which differs from the nucleophilic addition reactions of aldehydes and ketones.
