NEETChemistryCarboxylic Acid Derivatives
Why does the direct attachment of a phenyl or vinyl group to a carboxylic acid increase its acidity?
Options
- ADue to the presence of resonance structures
- BDue to the greater electronegativity of the attached carbon
- CDue to the electron-donating effect of the attached group
- DDue to the increase in steric hindrance
Correct answer
B. Due to the greater electronegativity of the attached carbon
Step-by-step solution
The paragraph explains that the increase in acidity of carboxylic acids when attached to phenyl or vinyl groups is due to the greater electronegativity of the attached carbon.
