Question

Which among the following is the strongest acid?

Options

• FCH₂CH₂COOH

• CH₃CH(F)COOH

• CICH₂CH₂COOH

• CH₃CH₂COOH

Answer 1

CH₃CH(F)COOH

Explanation:

As the negative charge is diffused, the electron removing substituents stabilise the carboxylate ion through inductive action. The strength of carboxylic acid is increased as a result of this. The substituent on the α-carbon atom is the most effective at boosting the acid's strength.

As the negative charge intensifies, the electron releasing substituents destabilise the carboxylate ion by inductive action. Carboxylic acid's strength is reduced as a result of this.

As a result, CH₃CH(F)COOH is the most powerful of the acids since it has a strong electron withdrawing group (i.e., - F).
