Subjective Type

Based on $$pK_a$$ values the order of decreasing acidity of carboxylic acid molecules containing EWG must be? $$CF_3COOH, \; CCl_3COOH, \; HCCl_2COOH, \; NO_2CH_2COOH, \; FCH_2COOH, \\ ClCH_2COOH, \; BrCH_2COOH, \; HCOOH, \; ClCH_2CH_2COOH, \; C_6H_5COOH, \; \\ C_6H_5CH_2COOH, \; CH_3COOH, \; CH_3CH_2COOH$$.

Solution

Order of decreasing acidity of given compounds based on $$pK_a$$:
$$CF_3COOH >HCF_2COOH>CFH_2COOH>NO_2CH_2COOH> CCl_3COOH>HCCl_2COOH>H_2CClCOOH>\\H_2CBrCOOH>C_6H_5COOH>C_6H_5CH_2COOH>HCOOH>CH_3COOH>CH_3CH_2COOH.$$
