Definitions:

Conformational Isomers

Molecules that have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space due to rotation around a single bond.

Structural Isomers

Molecules that have the same molecular formula but differ in the connectivity of their atoms.

Isomers

Compounds with the same molecular formula but different structures or spatial arrangements of atoms.

Newman Projection

A method of drawing a molecule to visualize the conformational relationship between different atoms or groups in terms of their spatial orientation, usually focusing on carbon-carbon bonds.
