The acidic strength of saturated aliphatic carboxylic acids depends mainly upon the inductive effect of the substituent and its position w.r.t., the -COOH group. Whereas electron donating substituents tend to decrease, electron withdrawing substituents tend to increase the acid sttrength. the acidic strength of aromatic carboxylic acids, on the other hand, depends upon both the inductive and the resonance effect of the substituents Q. Which of the followig is obtained when 4-methylbenzenesulphonic acid is hydrolysed with excess of sodium acetate?

1.	The acidic strength of saturated aliphatic carboxylic acids depends mainly upon the inductive effect of the substituent and its position w.r.t., the -COOH group. Whereas electron donating substituents tend to decrease, electron withdrawing substituents tend to increase the acid sttrength. the acidic strength of aromatic carboxylic acids, on the other hand, depends upon both the inductive and the resonance effect of the substituents Q. Which of the followig is obtained when 4-methylbenzenesulphonic acid is hydrolysed with excess of sodium acetate?
Answer» Solution :4-Methylbenzenesulphonic ACID is a stronger acid tha acetic acid, therefore, it displaces acetic acid from sdoium ACETATE. THUS, `4-Me-C_(6)H_(4)-SO_(3)H+CH_(3)COONa to 4-Me-C_(6)H_(4)SO_(3)^(-)Na^(+)+CH_(3)COOH`
