A skeletal formula is a three-dimensional model of the molecule that demonstrates the molecular shape, including bond angles. It does not necessarily display the elements within a molecule. These are drawn by using a line for each bond. Carbon atoms are understood to exist at each bend, conjunction, or end of a line. Hydrogen atoms are understood to be anywhere that they are required to give any atom the appropriate number of covalent bonds. All other elements are specifically noted in the appropriate place. Some common groups, such as benzene rings, have their own shorthand forms.
