WebA saw-horse model simply refers to only drawing lines and using letters for the elements in the molecule. A Newman projection is basically a "head on" view of the molecule that uses the same saw-horse drawing scheme (lines and letters). Eclipsed and staggered conformations are two types of ways that a molecule organizes is atoms. WebAnd within that staggered group we can have gauche and anti conformations.
