Which of the following is the correct order of acidic strength ?

A

`Cl_(2)C COOH gt Cl_(2)CHCOOH gt ClCH_(2)COOH gt CH_(2)COOH`

B

`CH_(2)COOH gt ClCH_(2)COOH gt Cl_(2)CHCOOH gt Cl_(2)C COOH`

C

`CH_(2)COOH gt Cl_(2)C COOH gt Cl_(2)CHCOOH gt ClCH_(2)COOH`

D

`CH_(2)COOH gt ClCH_(2)COOH gt Cl_(2)CHCOOH gt Cl_(2)C COOH`

Text Solution

Verified by Experts

The correct Answer is:
A
`-Cl` increases the polarity of `-overset(O)overset(||)(C) -` group because -Cl is electron withdrawing in nature.
Therefore, the acidic strength of the compounds are : `Cl_(3)C.COOH gt Cl_(3)CHCOOH gt ClCH_(2)COOH gt CH_(3)COOH`
