Q. The order of strengths of the following caboxylic acids is
(i) $CH_3-CH_2-COOH$
(ii) $CH_3-COOH$
(iii) $C_6H_5-COOH$
(iv) $C_6H_5-CH_2COOH$

AP EAMCETAP EAMCET 2018

Solution:

(i) $CH _{3}- CH _{2}- COOH$

(ii) $CH _{3}- COOH$

(iii) $C _{6} H - COOH$

(iv) $C _{6} H _{4}- CH _{2}- COOH$

Die to $-I$ effect (iii) is most acidic and order will be

$(iii) >( iv )>( ii )>( i )$.
