Question

The correct sequence of acidic strength of the following aliphatic acids in their decreasing order is :

\(CH_3CH_2COOH, CH_3COOH, CH_3CH_2CH_2COOH,HCOOH\)

(1) \(HCOOH > CH_3COOH > CH_3CH_2COOH > CH_3CH_2CH_2COOH \)

(2) \(HCOOH > CH_3CH_2CH_2COOH > CH_3CH_2COOH > CH_3COOH \)

(3) \(CH_3CH_2CH_2COOH > CH_3CH_2COOH > CH_3COOH > HCOOH \)

(4) \(CH_3COOH > CH_3CH_2COOH > CH_3CH_2CH_2COOH > HCOOH\)

Answer 1

Correct option is (1) \(HCOOH > CH_3COOH > CH_3CH_2COOH > CH_3CH_2CH_2COOH \)

\(CH_3CH_2COOH, CH_3COOH, CH_3CH_2CH_2COOH, HCOOH\)

The correct order is :

\(HCOOH > CH_3COOH > CH_3CH_2COOH > CH_3CH_2CH_2COOH\)
