Why are phenols more acidic than alcohols. Give two reactions to show that phenols are acidic in nature.

Answer»

Solution :Since the phenoxide ion left after the REMOVAL of a proton is stabilized by resonance whereas alkoxide ion (left after the removal of a proton from alcohol) is not. Therefore, phenols are more acidic than alcohols.
the TWO reactions of phenol showing its acidic natrue are:
`C_(6)H_(5)OH +NaOH to C_(6)H_(5)ON a+H_(2)O`
(II) Phenols react with metallic sodium to EVOLVE `H_(2)` gas.
`2C_(6)H_(5)OH+2Na to 2C_(6)H_(5)ON a+H_(2)`
