Draw the potential energy diagram for heptane upon rotation (of the C3-C4 bond) every 60 degrees. Label the x-axis "Rotation" and the y- axis "Potential Energy". Show the molecule in a Newman projection looking down the C3-C4 bond and draw each projection at the corresponding local maxima and minima.
