Question

give reason why direct attachment of vinyl group to carboxylic group increases the acidity of corresponding acids due to resonance​

Answer 1

Answer:

Direct attachment of groups such as phenyl or vinyl to the carboxylic acid, increase the acidity of the carboxylic acid is because of greater electronegativity of sp

2

hybridized carbon to which carboxyl carbon is attached.

Resonance with electron-donating groups decreases the acidity of carboxylic acid.

Explanation:

Hope it helps you

Thank you

Answer 2

Answer:

Direct attachment of groups such as phenyl or vinyl to the carboxylic acid, increase the acidity of the carboxylic acid is because of greater electronegativity of sp

2

hybridized carbon to which carboxyl carbon is attached.

Resonance with electron-donating groups decreases the acidity of carboxylic acid.

Hence, Option "C" is the correct answer.
