The increasing order of the acidity of the following carboxylic acids is:
Options
- AIII < II < IV < I
- BI < III < II < IV
- CIV < II < III < I
- DII < IV < III < I
Correct answer
A. III < II < IV < I
Step-by-step solution
The increasing order of the acidity of the carboxylic acids is III < II < IV < I. In aromatic acids, electron withdrawing groups like Cl ,- CN ,- NO ₂ increases the acidity, whereas electron releasing groups like CH ₃,- OH ,- OCH ₃,- NH ₂ decreases the acidity.
