NEETChemistryAldehydes and Ketones
Although phenoxide ion has more number of resonating structures than carboxylate ion, carboxylic acid is a stronger acid than phenol. Why?
Options
- AThe carboxylate ion is more stable due to inductive effect, which decreases its acidity compared to phenol.
- BPhenol has an oxygen atom, making it less acidic than carboxylic acid.
- CCarboxylic acid has two oxygen atoms that can stabilize the negative charge through resonance, making it a str
- DThe resonating structures of carboxylate ion contribute more towards its stability than those of phenoxide ion
Correct answer
D. The resonating structures of carboxylate ion contribute more towards its stability than those of phenoxide ion
Step-by-step solution
Correct Option is : (D) The resonating structures of carboxylate ion contribute more towards its stability than those of phenoxide ion. As a result, carboxylate ion is more resonance-stabilized than phenoxide ion. Hence, carboxylic acid is a stronger acid than phenol.
