Question:
What is the product obtained when ethylamine is heated with large excess of ethyl iodide?
What is the product obtained when ethylamine is heated with large excess of ethyl iodide?
Show Hint
Excess alkyl halide leads to quaternary ammonium salt formation.
Updated On: Feb 11, 2026
- Tetraethyl ammonium iodide
- Triethyl amine
- Diethyl amine
- Ethyl methyl amine
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Recall alkylation of amines.
Amines undergo successive alkylation with alkyl halides. In presence of excess alkyl halide, exhaustive alkylation occurs.
Step 2: Apply to ethylamine.
Ethylamine reacts repeatedly with ethyl iodide forming secondary, tertiary amines and finally a quaternary ammonium salt.
Step 3: Final product formation.
With large excess of ethyl iodide, the reaction proceeds to form tetraethyl ammonium iodide.
Step 4: Conclusion.
The final product is tetraethyl ammonium iodide.
