Question

Question: Convert each three-dimensional model to a Newman projection around the indicated bond.

Short answer

Answer

a.

Newman Projection

b.

Newman projection

c.

Newman projection

Step-by-step solution

Meaning of the Newman projection

The Newman projection is used to represent the different conformational isomers of alkanes. A dot represents the carbon in the front, and a circle represents the back carbon.

The dihedral angle between the front and the back carbons is illustrated specifically by the Newman projections.
