Question

give reason why trichloro acetic acid has more acidic characters than monochloro acetic acid ?
​

Answer 1

Answer:

Electron withdrawing group increases the acidic nature and electron releasing group decrease the acidic nature. Here trichloroethylene group is highly EWG via inductive effect therefore trichloroacetic acid stronger than dichloro or monochloro acetic acid.

Explanation:

Answer 2

Trichloro-acetic acid is more acidic because of more electronegativity.

• Acetic acid is the common name for ethanoic acid which is a carboxylic acid having two carbons.
• It is acidic in nature as it can release hydrogen ions in water along with carboxylate ions.
• When one/ two/ three chlorine atoms get attached to the carboxylic acid, it becomes more acidic because of an increase in electronegativity.
• With the increase in chlorine atoms, the electronegativity increases along with the increase in electron density on the oxygen atom.
• Thus, trichloro-acetic acid is more acidic than chloro-acetic acid.
