None of the given molecules display much solubility in water at room temperature. However, two of the molecules display appreciable solubility in boiling water. salicylic acid 2-naphthol acetaminophen Based on its structure, which molecule will be the least soluble in hot water?

2-naphthol, based on its structure will be least soluble in water.

2-Naphthol, or β-naphthol, is a fluorescent, colorless (or occasionally yellow) crystalline solid with the formula C10H7OH. It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol, but more reactive. Both isomers are soluble in simple alcohols, ethers, and chloroform. 2-Naphthol is a widely used intermediate for the production of dyes and other compounds.
