WebbAlcohols contain the polar -OH group. Short chain alcohols are water soluble and so hydrophile, while long chain alcohols are less water soluble, they are hydrophob, because most of the molecule contains apolar bonds. Molecules with ionic bonds, like NaCl are hydrophilic, but not necessary water soluble (e.g. AgCl is poorly soluble in water).

"A hydrophile is a molecule or other molecular entity that is attracted to water molecules and tends to be dissolved by water. In contrast, hydrophobes are not attracted to water and may seem to be repelled by it. Hygroscopics are attracted to water, but are not dissolved by water. Visa mer A hydrophilic molecule or portion of a molecule is one whose interactions with water and other polar substances are more thermodynamically favorable than their interactions with oil or other hydrophobic solvents. … Visa mer • Hydrophilic-lipophilic balance • Hydrophobicity scales • Superhydrophilicity • Ultrahydrophobicity • Wetting Visa mer Liquid hydrophilic chemicals complexed with solid chemicals can be used to optimize solubility of hydrophobic chemicals.
