called conformations, and a specific conformation is called a conformer.
In drawing conformations, we often use Newman projections, a way of drawing a molecule looking straight down the bond connecting two carbon atoms.
Dihedral angle θ:- the angle between the C-H bonds on the front carbon atom and the C-H bonds on the back carbon in the Newman projection.
Eclipsed conformation:- Any conformation with bonds directly lined up with each other, one behind the other, in the Newman projection. The conformation with θ = 0o is an eclipsed conformation
Staggered conformation:- Any conformation with the bonds equally spaced in the Newman projection. The conformation with θ = 60° is a staggered conformation.
Torsional strain:- The strain associated with eclipsing of bonds in the ring.
Conformers of butane: CH3-CH2-CH2-CH3
Cyclohexane Conformations: The actual structure of cyclohexane.
The least stable conformation is the boat conformation.
