Choose the weakest acid among the following

Question

Choose the weakest acid among the following (A)  F3C - COOH  (B)  F-CH2- COOH  (C)  CH3 - COOH  (D)  CH3 - CH2 - COOH

Tardigrade Admin · Accepted Answer

The acidity of carboxylic acids depends upon the nature of the alkyl group attached to COOH . The presence of an electron-withdrawing ( -I effect) group weakens the OH bond in the acid and increases the acidity, while the presence of an electron releasing ( +I effect) group strengthens the OH bond of acid and thus, decreases the acidity. Thus, the weakest acid is, underset2-methylpropanoic text acid mathopCH3- overset beginsmallmatrix CH3 | endsmallmatrix mathopCH -COOH

Q. Choose the weakest acid among the following

$F_{3} C - COO H$

$F - C H_{2} - COO H$

$C H_{3} - COO H$

$C H_{3} - C H_{2} - COO H$

$(C H_{3})_{2} C H - COO H$

Q. Choose the weakest acid among the following

F3​C−COOH

F−CH2​−COOH

CH3​−COOH

CH3​−CH2​−COOH

(CH3​)2​CH−COOH

$F_{3} C - COO H$

$F - C H_{2} - COO H$

$C H_{3} - COO H$

$C H_{3} - C H_{2} - COO H$

$(C H_{3})_{2} C H - COO H$
