Alcohols are acidic in nature because hydrogen is attached to oxygen which is an electronegative element. Alcohol is weaker acid than water because `OH^(-)` ion is more stable than `R-O^(-)` ion. `R-O^(-)` is less stable, due to `+I` effect of the alkyl group. Acidity of alcohols increases with increase in the stability of acid anion.

Some alcohol like `CH_(3)-OH, CF_(3)-CH_(2)-OH, (CF_(3))_(3)C-OH` ae more acidic than water.
Which among the following is the most acidic ?

Options

A. HOH
B. `CH_(3)OH`
C. `CH_(3)-CH_(2)-OH`
D. `CH_(3)-CH_(2)-CH_(2)-OH`

Answer

A
