The different ways to draw organic molecules include Lewis-type, condensed formulae, and skeletal formulae. Through general chemistry, you may have already experienced looking at molecular structure. Another good idea is to get a model kit and physically make the molecules that you have trouble picturing in your head. At first it may seem difficult or overwhelming, but the more you practice looking at and drawing organic molecules, the more familiar you will become with the structures and formulae. Some people say that organic chemistry is like another language, and in some aspects, it is. Learning and practicing the basics of organic chemistry will help you immensely in the long run as you learn new concepts and reactions. In addition, some of these shorthand ways of drawing molecules give us insight into the bond angles, relative positions of atoms in the molecule, and some eliminate the numerous hydrogens that can get in the way of looking at the backbone of the structure. It is tedious to constantly draw out every detail, especially when not necessary, so organic chemists developed ways to make it more convenient and easy. Why were different drawing techniques developed? Organic molecules can get complicated and large.

Here you will learn how to understand, write and draw organic molecules. 1: Representations of 1–bromobutane: Skeletal structure, Lewis–type structure, InChI string, InChIKey, SMILES and CAS Registry Number. 1 illustrates some of the most common representations for the compound with the name 1-bromobutane. Sometimes structures need to be represented in other ways, such as a name or other identifier.

Full Lewis structures are used only rarely, when a more complete drawing is needed, because they are often harder to read than skeletal structures. Chemical structures are usually represented by the skeletal formula, which provides a graphical representation of the molecule with most hydrogens omitted for clarity. They make up the “words” of every organic chemistry sentence, so it is vital to understand how to read and write structures. Representing a chemical structure Chemical structures are the essential building blocks in organic chemistry.
