प्रश्न
Arrange the following in decreasing order of their acidic strength and give reason for your answer.
\[\ce{CH3CH2OH, CH3COOH, ClCH2COOH, FCH2COOH, C6H5CH2COOH}\]

उत्तर
The order is
\[\ce{ClCH2COOH > FCH2COOH > C6H5CH2COOH > CH3COOH > CH3CH2OH }\]
When compared to other alcohols \[\ce{CH3CH2OH}\] is the least acidic. Because of the halogen, \[\ce{FCH2COOH}\] is quite acidic. It is either an electron-donating group or an electron receiving group in acidic strength. Acidic strength increases as the number of electron withdrawing groups increases. The acidic strength of electron-donating groups diminishes.
