Displayed Formula, Structural Formula and Skeletal Formula

In this video, we look at how the use the displayed formula, structural formula and skeletal formula of organic compounds. I start by comparing displayed and structural formulas. I explain to you how to show functional groups and side-chains in the structural formula by using brackets. We then look at skeletal formula. I show you the rules for drawing skeletal formula and then explain how to represent a functional group on a skeletal formula.
