The condensed structural formula is an intermediate representation of the above two. It is a formula written in a way that suggests the bonding of the atoms: ethanol's condensed structural formula is CH3CH2OH. Note that this is the same way that the atoms in the above structure are connected: the first three hydrogens to the carbon, the first carbon to the second carbon, which in turn is bonded to two hydrogens and one oxygen, and finally the oxygen is bonded to one hydrogen.
Example: The structural form of the molecule ethyl methyl ether is
shown below. What is the molecular formula and condensed structural formula for
ethyl methyl ether?
Solution: To get the molecular formula, simply count the number of
atoms in the structure. There are three carbons, one oxygen and eight hydrogens,
so the molecular formula of ethyl methyl ether is
