Answer 2

Increasing order of acidic strength is  $CH_3COOH$ <$HCOOH$<$ClCH_2COOH$ < $FCH_2COOH$

Explanation:

The acidic strength depends on the stability of the resulting carboxylate ion.

The presence of electron donating groups enhance the negative charge on carboxylate ion and thus decrease the stability of acids and thus make the acid less acidic. Thus presence of electron withdrawing groups which withdraws the electrons from negatively charged oxygen of carboxylate results in more stability and hence make the acid more acidic.

$RCOOH\rightarrow RCOO^-+H^+$

Thus the order is : $CH_3COOH$ <$HCOOH$<$ClCH_2COOH$ < $FCH_2COOH$

as $CH_3$ is electron donating , Cl and F are electron withdrawing in nature where F is more electron withdrawing due to more electronegativity.
