Vedclass · Answer

(C) dihydric compound contains two hydroxyl $(-OH)$ groups attached to the benzene ring.$1$. Catechol ($1,2$-dihydroxybenzene) is a dihydric phenol.$2$. Resorcinol ($1,3$-dihydroxybenzene) is a dihydric phenol.$3$. Hydroquinone ($1,4$-dihydroxybenzene) is a dihydric phenol.$4$. Phloroglucinol ($1,3,5$-trihydroxybenzene) contains three hydroxyl groups,so it is a trihydric phenol.Therefore,Phloroglucinol is $NOT$ a dihydric compound.
