Question

Sodium phenoxide when heated with ${\mathrm{CO}}_2$ under pressure at $125°\mathrm{C}$produces ______.

• A. Salol
• B. Salicylaldehyde
• C. Sodium benzoate
• D. Sodium Salicylate

Answer 1

The correct option is D

Sodium Salicylate

Explanation:

Reaction of Sodium phenoxide with carbon dioxide:

• When Sodium phenoxide when heated with ${\mathrm{CO}}_2$ under pressure at $125°\mathrm{C}$produces Sodium salicylate.
• The acidification of Sodium salicylate leads to the formation of 2 - hydroxybenzoic acid(Salicyclic acid).
• The above reaction is known as Kolbe's reaction.

Therefore, the correct option is (D).
