Rank in order the strongest to the weakest acid cbr3cooh, ch3cooh and ccl3cooh

Answer 1

Answer: Rank in order the strongest to the weakest acid is
`CCl_(3)COOH` >
`CBr_(3)COOH` >
`CH_(3)COOH`.

Step-by-step explanation:

More readily a substance is able to donate a hydrogen ion more will be its acidic strength. Hence, stronger will be the acid.

More is the electronegativity of atoms attached to the acid more easily it will donate a proton. Hence, more will be its acidic strength.

Chlorine is more electronegative in nature as compared to bromine. So,

`CCl_(3)COOH` is more acidic than
`CBr_(3)COOH`.

Since there is no electronegative group attached to
`CH_(3)COOH` so it is least acidic than
`CCl_(3)COOH` and
`CBr_(3)COOH`.

Thus, we can conclude that rank in order the strongest to the weakest acid is
`CCl_(3)COOH` >
`CBr_(3)COOH` >
`CH_(3)COOH`.
