Answer:
[tex]$CF_3CO_2H> CHF_2CO_2H>CH_2FCO_2H>CH_3CO_2H$[/tex]
Explanation:
Florine has the highest electronegativity and it thus pulls the element of [tex]$OH^-[/tex] groups in the COOH group towards itself, making it relatively easy to loose the proton of the carboxyl group.

Those substances which release H+ ion when mixed in the solution is called acid.
The strength of the acid depends on the following:-
- Concentration of H+
The lewis structure state and define the number of electrons in the outermost shell of the electrons and help us to find the valency.
According to the question, we have to find the weakest carboxylic acid. Therefore the sequence are in increasing order and it is as follows:-
[tex]CF_3Co_2H[/tex]>[tex]CHF_2CO_2H[/tex]>[tex]CH_2FCO_2H>CH_3CO_2H[/tex]
This is the increasing order of the compounds.
