Vedclass · Answer

(A) dihydric compound is one that contains two hydroxyl $(-OH)$ groups in its structure.$1$. Crotonyl alcohol $(CH_3-CH=CH-CH_2OH)$ contains only one $-OH$ group,so it is a monohydric alcohol.$2$. Resorcinol $(C_6H_4(OH)_2)$ contains two $-OH$ groups attached to the benzene ring,so it is a dihydric phenol.$3$. Ethylene glycol $(HO-CH_2-CH_2-OH)$ contains two $-OH$ groups,so it is a dihydric alcohol.$4$. Quinol $(C_6H_4(OH)_2)$ contains two $-OH$ groups attached to the benzene ring,so it is a dihydric phenol.Therefore,Crotonyl alcohol is not a dihydric compound.
