Question:
The strongest base among the following is
The strongest base among the following is
Show Hint
Negative charge → very strong base
Resonance reduces basicity
Aniline is weak due to delocalization
Updated On: May 1, 2026
- amide ion
- hydroxide ion
- trimethylamine
- ammonia
- aniline
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept: Basic strength depends on:
• Availability of lone pair
• Charge on species
• Stability of conjugate acid Comparison:
• Amide ion (NH$_2^-$): negative charge → very high electron density → strongest base
• OH$^-$: strong but less than NH$_2^-$
• Trimethylamine: electron donating groups increase basicity
• Ammonia: moderate base
• Aniline: lone pair delocalized → weakest Conclusion: \[ \text{NH}_2^- \text{ is the strongest base} \]
