Which of the following represents the correct order of the acidic strength in the given compounds ?

A

`FCH_2COOH gt CH_3COOH gt BrCH_3COOH gt ClCH_2COOH`

B

`BrCH_2COOH gt ClCH_2COOH gt FCH_2COOH gt CH_3COOH`

C

`FCH_2COOH gt ClCH_2COOH gt BrCH_2COOH gt CH_3COOH`

D

`CH_3COOH gt BrCH_2COOH gt ClCH_2COOH lt FCH_2COOH`

Text Solution

Verified by Experts

The correct Answer is:
C
The acidity of halogenated acid increases with increase in electronegativity of the halogen present. The electronegativity of the halogen decreases in order as F gt Ce gt Br. Therefore correct order of given compound is
`FCH_2COOH gt ClCH_2COOH gt BrCH_2COOH gt CH_3COOH`
