Arrange the following acid in decreasing order of their acidic strength :
(I) `CH_(3)-OH` (II) `CH_(3)CH_(2)-OH`
(III) `CH_(3)-underset(CH_(3))underset(|)(CH)-OH` (IV) `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-OH`

Options

A. `(III)lt(II)lt(I)`
B. `(I)lt(II)lt(III)`
C. `(II)lt(I)lt(III)`
D. `(I)=(II)=(III)`

Answer

A

Explanation

(a) Formic acid (HCOOH) is the strongest acied while propionic acid `(CH_(3)CH_(2)COOH)` is the weakest acid. Therefore, it is the correct order of esterification
