Increased substitution around a bond leads to increased strain. Take the four substituted butanes listed below, for example. For each compound, sight along the C2-C3 bond and draw Newman projections of the most stable and least stable conformations. Use the data in Table 3-5 to assign strain-energy values to each conformation. Which of the eight conformations is most strained? Which is least strained? (a) 2-Methylbutane (b) 2,2-Dimethylbutane (c) 2,3-Dimethylbutane (d) 2,2,3-Trimethylbutane
5. Draw the two chair conformations ("ring filips") of trans –1- ethyl-4-methylcyclohexane to show the axial and equatorial substituents (including all hydrogens). Then determine which of the two conformations is more stable and why.
Rank the conformations of n-butane with reference to its potential energy from the most stable to the least stable. Rank from the most stable to the least stable. To rank items as equivalent, overlap them.

Analyze the two Newman projections and determine the relationship between the two. How would you describe the relation between conformations when they are maintained at a temperature too low to permit them to interconvert? CH3 CH3 Br. H H H H A. Identify the relationship. They are identical. They are structural isomers. They are stereoisomers. They are conformers. H H -I H Br H B. What is the relationship at low temperatures? They are identical. They are conformational diastereomers. They are structural isomers. They are conformational enantiomers.

Construct a model of chloroethane, CH3CH2Cl. Remember that these models do not actually show the relative sizes of different atoms. View the model along the carbon-carbon axis and draw the sawhorse and Newman projections of the preferred conformation.

For each of these cycloalkanes, which are partly skeletal (line) drawings, and also have two or three methyl groups attached to them, add the hydrogens which are not shown (the hydrogens on the methyl C's are already indicated as you see). Determine the molecular formula (C_H for each. H3C CH3 H;C. CH3 H3C- CH3 CH3 C 7 H C_ H C H
