What is the name of the 1,3-isomer (or meta-isomer) of benzenediol with the chemical formula C6H4 (OH)2?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Resorcinol.
The 1,3-isomer (or meta-isomer) of benzenediol with the chemical formula C₆H₄(OH)₂ is Resorcinol. Resorcinol features two hydroxyl groups (-OH) attached to the benzene ring at the meta positions relative to each other. It is distinct from catechol (1,2-isomer) and m-cresol (1,3-isomer of toluene), and glycerol is not a benzenediol but a trihydroxy alcohol.
