(a)
Interpretation: The given three-dimensional model is to be converted to a Newman projection around the indicated bond.
Concept introduction: Newman projection is a visual representation of a conformation. It describes three groups which are attached to each carbon atom in a particular
Dihedral angle is the angle between two planes that originates due to the presence of different atoms in a Newman projection.
