Chem 301: I need help with drawing (3R,4S)-3,4-dimethylhexane

Question

Draw (3R,4S)-3,4-dimethylhexane. Use wedges and dashes to show stereochemistry.

Please draw all four bonds at chiral centers. Use wedge and dash bonds at chiral centers only. Do not use wedges and dashes at non-chiral centers.

Answer 1

A chiral center is an atom that has that has four different atoms or groups attached to it. C3 and C4 are your chiral centers. Be sure to add your extra H-bonds at those locations because your instructions want you to draw all four bonds at chiral centers.
