When alkyl iodide is treated with large excess of ammonia, the major product obtained is:
When alkyl iodide is treated with large excess of ammonia, the major product obtained is:
Show Hint
When excess ammonia is used, primary amine is the major product due to nucleophilic substitution.
Updated On: Feb 24, 2026
- Tertiary amine
- Quaternary ammonium salt
- Secondary amine
- Primary amine
Show Solution
The Correct Option is D
Solution and Explanation
Treating alkyl iodide with excess ammonia results in primary amine formation. This occurs through nucleophilic substitution, where ammonia (NH$_3$) substitutes the iodine atom on the alkyl iodide. While further substitution can yield secondary or tertiary amines in the presence of excess ammonia, the primary amine is the predominant product.
