Final answer:
The Newman projection of an eclipsed conformation for propane is when the hydrogen atoms on one carbon are directly in front of the hydrogen atoms on the adjacent carbon.
Step-by-step explanation:
The Newman projection of an eclipsed conformation for propane is when the hydrogen atoms on one carbon are directly in front of the hydrogen atoms on the adjacent carbon. This results in the highest energy conformation due to increased steric repulsion between the hydrogens. The correct Newman projection is:
H |
H-C-C-H

H
