Electronegativity of water correct answers The different electronegativities of hydrogen and oxygen make water a polar molecule capable of forming hydrogen bonds. This makes water a good solute. Hydrophobic interactions correct answers Non-polar hydrophobic compounds dissolve poorly in water. These compounds minimize their surface area exposed to water by forming aggregates in which the hydrophobic groups go to the interior through hydrophobic interactions. Only the more polar portions intera...
