Reaction Chart of Acid Amide (R-CONH₂)
Acid amides are stable carboxylic acid derivatives that play a significant role in polymer chemistry and biochemistry, frequently appearing in Organic Chemistry syllabus for JEE and NEET.
Unlike acid chlorides, amides are less reactive but undergo highly specific and important named reactions. Understanding the Hoffmann Bromamide Degradation, dehydration to nitriles, and reduction to primary amines is critical for solving organic conversion problems.
This reaction chart provides a concise summary of amide chemistry, helping you visualize the transformation paths for primary, secondary, and tertiary amides during your quick revision.

High-Yield Revision Points
- Hoffmann Bromamide Degradation: Amide reacts with Br2/KOH to give a primary amine with one less carbon atom.
- Dehydration: P2O5 or SOCl2 dehydrates primary amides to form Alkyl Nitriles (R-CN).
- Reduction: LiAlH4 reduces amides directly to amines (unlike nitriles which can be reduced to aldehydes with DIBAL-H).
- Hydrolysis: Acidic or basic hydrolysis of amides yields Carboxylic Acids and Ammonia/Amines.
