Question

Phenol turns blue litmus red while alcholols donot?Explain?

Answer 1

Alcohols are so weakly acidic that, for normal lab purposes, their acidity can be virtually ignored. However, phenol is sufficiently acidic for it to have recognisably acidic properties - even if it is still a very weak acid. A hydrogen ion can break away from the -OH group and transfer to a base.

Acids turn blue litmus red but no change is observed in red litmus.

Hope this helps
