key term - Newman projection

Definition

A Newman projection is a method used in organic chemistry to visualize the spatial arrangement of bonds and atoms in a molecule from a specific viewpoint, which is looking down the bond axis connecting two carbon atoms. This visual representation helps in understanding the different conformations (spatial arrangements) that molecules can adopt due to rotation around single bonds.

Related terms

Conformational Isomerism:

It refers to molecules that have the same molecular formula but differ in the orientation of their atoms in space due to rotation around single bonds.

Staggered Conformation:

This is a type of molecular conformation where atoms or groups attached to adjacent carbons are positioned as far apart as possible, leading to lower energy and more stability.

Eclipsed Conformation:

This refers to a conformation where atoms or groups attached to adjacent carbons align with each other, leading to higher energy and less stability due to increased electron repulsion
