Unformatted text preview: 2 CH 2 Cl has a dipole moment of 1.12 D, it can exist entirely in the gauche conformation or it can be a mixture of anti and gauche con-formations, but it cannot exist entirely in the anti conformation. Statement 1 is false. 3.37–3.40 Solutions to molecular modeling exercises are not provided in this Study Guide and Solutions Man-ual. You should use Learning By Modeling for these exercises. SELF-TEST PART A A-1. Draw Newman projections for both the gauche and the anti conformations of 1-chloro-propane, CH 3 CH 2 CH 2 Cl. Sight along the C-1, C-2 bond (the chlorine is attached to C-1).
