Three-Dimensional Representations: Cyclic Structures

Cyclic, or ring, structures can also be drawn in a variety of ways. Rings can have many different sizes, with the smallest ring being cyclopropane (three carbons). The most common ring types in organic chemistry are cyclopentane (five carbons) and cyclohexane (six carbons). Cyclohexane will be discussed in this tutorial, and its three main structural types can be seen above. From left to right, these structures are the Wedge-Dash Notation, the Haworth Projection, and the Chair Conformation.
