Stereochemistry, Newman Projections and Chair Conformations

This solution:

1) Gives the most stable chair conformer of (1 R, 2 R)-1-bromo-2-chlorocyclohexane.

2) Provides a Newman projection of this conformer.

3) Provides all stereoisomers of 1, 3-dibromocyclohexane.

4) Identifies these stereiosomers as enantiomers, diasteresomers, or meso.
