Question

multiple choice 2 points identify the marked dihedral angle in the given newman projection. 120° 180° 0° 60° previous

Explanation:

Step1: Recall dihedral - angle definition

The dihedral angle in a Newman projection is the angle between two bonds on adjacent atoms.

Step2: Analyze given Newman projection

In the given Newman projection, the chlorine ($Cl$) atom and the hydrogen ($H$) atom are eclipsed. When two groups are eclipsed, the dihedral angle between the bonds to these groups is $0^{\circ}$.

Answer:

C. $0^{\circ}$
