Naming Substituted Alkanes 1. Find the parent Find the longest continuous carbon chain of carbon atoms present in the molecule, and use the name of that chain as the parent (root, stem). CH 3 CH H 2 C CH 3 CHCH 2 CH 3 CH 2 CH 2 CH 3 1 2 3 4 5 6 7 Name as a substituted hexane with two substituents, not a substituted hexane with one substituent. If two chains of equal length are present, choose the one with larger number of branch points. CH 3 CH 2 H 2 C CH 3 CH 2 CH 2 CH 3 1 2 3 4 CH CH 3 5 6 CH 3 CH 2 H 2 C CH 3 CH 2 CH 2 CH 3 1 2 3 4 CH CH 3 5 6 2) Number the atoms in the main chain a. Beginning at the end nearer the first branch point, number the carbons in the longest chain.

If there is branching an equal distance away from each end, use the alphabet to decide how to number. The substituent that come first in alphabetical order is attached to lower number carbon. If there are more
