Question
Compare and explain the relative Bronsted basicities of 1°, 2° and 3° alcohols in the liquid state.
Solution
Bronsted base is H+ ion acceptor, therefore, more of the electron releasing alkyl groups at α-carbon, more the electron density on oxygen atom and more the tendency to accept H+ ion. Hence, the basicity of alcohol is in order of,
3° > 2° > 1°
3° > 2° > 1°
