Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

Phenols are much more acidic than alcohols but less so than carboxylic acids or even carbonic acid. This is indicated by the values of ionisation constants. The relative acidity follows the order:

${\mathrm{K}}_{\mathrm{a}}\underset{\mathrm{R}\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}}{10^{-5}}>\underset{{\mathrm{H}}_2\mathrm{C}{\mathrm{O}}_3}{10^{-7}}>\underset{{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\mathrm{H}}{10^{-10}}>\underset{\mathrm{H}\mathrm{O}\mathrm{H}}{10^{-14}}>\underset{\mathrm{R}\mathrm{O}\mathrm{H}}{10^{-18}}$
