Question

List in order of most acidic to least acidic:

\(CHF_2CH_2CH_2CO_2H\)
\(CH_3CF_2CH_2CO_2H\)
\(CH_3CH_2CF_2CO_2H\)
\(CH_3CH_2CH_2CO_2H\)

Answer 1

Acidity is the measure of the tendency of acidic H to go in to the solution.
C. is the most acidic, as two florine atoms are very electro negative, and pull on them the e- form the C, which after that pulls e- from COOH.
