D. Newman Projection Energy Diagrams. 14. Draw a qualitative energy diagram for CH3CHCHCH(CH3)2, relative to the bond between the two CH2 carbons. The Newman projections are drawn below, using "iPr" as an abbreviation for the isopropyl CH(CH3)2 group. Put "S" (for staggered) by any "staggered" conformation, and "E" (for eclipsed) by an eclipsed conformation. iPr iPr 44 iPr CH3 H CH3 H H H CHH3 H H iPd H H CH3 H3 iPr H HC H iPr H H H 44 iPr CH3
