See Figure 3-8. Which structure does NOT fit a molecule with 6 degrees of unsaturation? A B с D

O HYDROCARBONS Identifying bond rotations in dash-wedge skeletal structures Examine the highlighted labeled bond in the structure below. Can the highlighted labeled bond rotate 180° without breaking any bonds in the molecule? If this bond can rotate, select all of the structures that a 180° bond rotation could make. Explanation OH Check yes no OH OH OH OH HO 1/5 s OH

Q8 Conformational Analysis of Cycloalkanes In this question you will look at the conformations of the following molecule: CH3 C В F CH3 D -E A H3C F I II Energy Costs for Interactions in Alkane Conformers: Computed Energy Cost (kJ/mol)* 3.8 Interaction H+H eclipsed H+CH3 eclipsed CH3+CH3 eclipsed CH3+CH3 gauche H»CH(CH3)2 gauche H CH(CH:)2 eclipsed CH3+CH(CH3)2 gauche CH3+CH(CH3)2 eclipsed HeC(CH:)3 eclipsed CH3+C(CH3)3 gauche CH3+C(CH:)3 eclipsed H+I eclipsed I+CH3 gauche I+CH3 eclipsed "Values computed with Gaussian09 using B3LYP/6-31G(d) for structure optimization and B3LYP/6-311+G(2df,3p) for the conformation energy. The calculations were performed in the gas phase (no solvent). *This result for t-butyl is a bit peculiar given that the value is less than that for isopropyl, but there is an explanation that I can tell you about in office hours! 4.8 12.6 3.7 (0.0) 3.1 3.6 17.3 2.8 13.6 18.7 6.7 1.2 15.5 Steric Strain in Monosubstituted Cyclohexanes: 1,3-Diaxial strain Y (kJ/mol)…
