Sawhorse representation

Definition

A sawhorse representation is a method used in organic chemistry to depict the three-dimensional spatial arrangement of bonds in molecules, specifically focusing on staggered and eclipsed conformations of alkanes like ethane. It shows the molecule from a slightly angled side view, allowing for easier visualization of the spatial relationships between atoms or groups.

Related terms

Staggered conformation:

A molecular arrangement where atoms or groups are positioned around a central bond so that they are as far apart as possible, minimizing electron repulsion.

Eclipsed conformation:

A less stable molecular arrangement where atoms or groups directly align with each other across a central bond, maximizing electron repulsion due to their close proximity.

Newman projection:

Another method of visualizing the three-dimensional structure of molecules by looking straight down the bond connecting two carbon atoms, useful for comparing different conformations' stability
