How many total positional isomers of dihydric phenols are possible for the molecular formula ? — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

For $C_6H_6O_2$ representing dihydric phenols, the two hydroxyl groups can be placed on the benzene ring in ortho (1,2), meta (1,3), or para (1,4) positions, yielding exactly 3 isomers (Catechol, Resorcinol, Hydroquinone).
