Identify trihydric phenol from following.

Options

AHydroquinone
BCatechol
CO-Cresol
DPyrogallol

Correct answer

D. Pyrogallol

Step-by-step solution

Trihydric phenols are compounds that contain three hydroxyl ( -OH ) groups attached directly to the benzene ring. Hydroquinone is benzene-1,4-diol, which contains two -OH groups and is a dihydric phenol. Catechol is benzene-1,2-diol, which contains two -OH groups and is a dihydric phenol. o-Cresol is 2-methylphenol, which contains one -OH group and is a monohydric phenol. Pyrogallol is benzene-1,2,3-triol, which contains three -OH groups and is a trihydric phenol. Answer: Pyrogallol
