Question

which one of the following is the correct order of acidic strength? (i) Cl3C-COOH (ii) Cl2CH-COOH (iii) ClCH2-COOH (iv) CH3-COOH (A) iv > iii > ii > i (B) i > ii > iii > iv (C) I > iii > ii iv (D) iv > ii > iii > i

Acidic nature propto - textI (Electron withdrawing groups) More the - textI group at α 'C' of carboxylic acid greater the acidic strength. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-o6dy17ykf76m.png" />

Q. which one of the following is the correct order of acidic strength?

(i) $C l_{3} C - COO H$

(ii) $C l_{2} C H - COO H$

(iii) $ClC H_{2} - COO H$

(iv) $C H_{3} - COO H$

iv > iii > ii > i

i > ii > iii > iv

I > iii > ii iv

iv > ii > iii > i

Acidic nature $\propto$ $- I$ (Electron withdrawing groups)

More the $- I$ group at $α$ 'C' of carboxylic acid greater the acidic strength.
