Which is the strongest acid, CCl3COOH or CH2ClCOOH please explain WHY it is stronger.
Ccl3cooh
i think 1 is strong acid because it contain more cl atom than the second one and cl is more electron with drawing and more the cl atom it attract the carboxyal group toward itself.
To determine the strength of an acid, we need to look at its chemical structure and characteristics. In this case, we are comparing two acids: CCl3COOH (trichloroacetic acid) and CH2ClCOOH (chloroacetic acid).
First, let's analyze the structure of these acids:
CCl3COOH (trichloroacetic acid):

CH2ClCOOH (chloroacetic acid):

C — C — OH

Cl
The strength of an acid is determined by its ability to release protons (H+ ions) in solution. The more readily an acid donates a proton, the stronger it is.
In this case, trichloroacetic acid (CCl3COOH) is stronger than chloroacetic acid (CH2ClCOOH). This is because the presence of three chlorine atoms in trichloroacetic acid increases its electron-withdrawing effect, making it more acidic. The chlorine atoms pull electron density away from the carbon atom and weaken the bond between the carbon and the oxygen atom.
As a result, the acidity of trichloroacetic acid is enhanced, allowing it to more easily donate a proton in a chemical reaction. In contrast, chloroacetic acid has only one chlorine atom, causing it to be less electron-withdrawing and less acidic compared to trichloroacetic acid.
Therefore, when comparing CCl3COOH and CH2ClCOOH, trichloroacetic acid (CCl3COOH) is the stronger acid due to the presence of three chlorine atoms, which increase its acidity by withdrawing electron density from the carbon-oxygen bond.
