The given dissociation constant (Ka) value 1.3x10⁻¹⁰ is of?
Correct answer: D. Phenol
- A. Alcohol
- B. Acetic acid
- C. Water
- D. Phenol
Explanation
The given dissociation constant (Ka) value of 1.3x10⁻¹⁰ is characteristic of phenol.The dissociation constant (Ka) is a measure of the extent to which an acid dissociates in aqueous solution. A lower value of Ka indicates a weaker acid. Phenol is a weak acid compared to strong mineral acids like hydrochloric acid (HCl) or sulfuric acid (H2SO4).

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.
