http://chemed.chem.purdue.edu/genchem/topicreview/bp/1organic/chirality.html WebAll 6 carbons can't all go away from you. However, every other carbon faces toward you. Therefore, you should draw it as a horizontal line. For 6 carbons (assuming this is hexane), the pattern would be horizontal, vertical, horizontal, vertical, horizontal, and then vertical. Hopefully that answers your question! ;) 3 comments ( 6 votes) Upvote
