Increasing order of acidic nature. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-q24kae7rqh5a.png" /> Electron withdrawing group, increases the acidity of benzoic acid, O-isomer will have higher acidity then corresponding m and p-isomer due to ortho effect.

Q. Which of the following is correct order for acidity of the given carboxylic acids?

$(A) P h COO H$

$(B) o - N O_{2} C_{6} H_{4} COO H$

$(C) p - N O_{2} C_{6} H_{4} COO H$

$(D) m - N O_{2} C_{6} H_{4} COO H$

$b > d > a > c$

$b > d > c > a$

$a > b > c > d$

$b > c > d > a$

Increasing order of acidic nature.

Electron withdrawing group, increases the acidity of benzoic acid, O-isomer will have higher acidity then corresponding m and p-isomer due to ortho effect.
