Water molecules are polar. As a result, they attract each other. Draw a second water molecule on the figure above. Your drawing should show: • The bond(s) between the two molecules • The name of the bond • The charges on each atom. [Total 3 marks] 2. Ponds provide a very stable environment for aquatic organisms. Three properties of water that
More important for biological systems, the carbon-to-hydrogen bonds are nonpolar covalent, which means that lipids are fat soluble and will not dissolve in water. There are four biologically important lipids: Fats; Waxes; Phospholipids; Steroids; Fats. Fats are large molecules that are composed of three fatty acid molecules bonded to a glycerol ...

For molecules that are not so electron-rich, naïve counting doesn’t suffice. The Lewis approach has no hope of getting the right answer for such molecules, and cannot be repaired or extended. In pleasant contrast, the molecular-orbital description does of course get the right answer.
