The reaction of carbolic acid with caustic soda is used to produce colorless product. The molecular formula of the product is:
Correct answer: D. C6H5ONa
- A. C6H6ONa
- B. C7H6O
- C. C6H5OH
- D. C6H5ONa
Explanation
Phenol (carbolic acid) is acidic and reacts with a strong base like sodium hydroxide (caustic soda) in an acid-base reaction. The products are water and the salt sodium phenoxide, which has the formula C₆H₅ONa.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
