Alcohol reacts slowly with Na metal compared to water because it has low concentration of H+ ion which suggests that it is:
Correct answer: A. Less acidic than water
- A. Less acidic than water
- B. Less basic than phenol
- C. More acidic than phenol
- D. More acidic than water
Explanation
The concentration of H+ ions determines the acidity. More H+ ions means the solution is more acidic as in the case of water while alcohol has a low concentration of H+ ions so it is less acidic than water.

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
