2. Conformational Isomers:
Conformational isomers are compounds that differ only by rotation about one or more single bonds.
Essentially, these isomers represent the same compound in a slightly different position-- analogous to a person who may be either standing up or sitting down.
These different conformations can be seen when the molecule is depicted in a Newman projection.
