# Which chemical properties make a substance hydrophilic?

The reason a substance can be dissolved in water or is hydrophilic is that of how easy it can bond with Water. Water is a highly polar molecule with $\delta$ positive hydrogens and a $\delta$ negative oxygen atom, this means that molecules containing polar groups, for example, Vitamin C or alcohols, are highly hydrophilic due to their ease of forming dipole-dipole interactions with water, because they contain highly polar $O H$ groups.
