Document Summary
Water"s ability to stick to itself makes it __________ Energy at which water forms hydrogen bonds= ____________ 4, with an average of 3. 4 bonds in liquid h2o. It weakens electrostatic forces and hydrogen bonds by competing for attractions. Soluble because of the 5 hydroxyl groups that are capable of hydrogen bonding. Molecules that cannot interact with water and therefore do not dissolve in the presence of water. When non-polar molecules within water tend to cluster together. This phenomenon occurs because of water is very cohesive. Is the hydrophobic effect spontaneous or spontaneous spontaneously because when the cluster forms the entropy of the system increases. When molecules have both hydrophilic and hydrophobic properties. Sds contains a polar sulfate group and a 12 carbon tail. Four types of non-covalent bonds: electrostatic (ionic, hydrogen bond, van der walls, hydrophobic interactions. Electrostatic interactions attraction based on charge with a distance between ions of approx.
