From: ·Steve·         Br         | CH3–CH2–CH–CH2–CH2–CH2–OH 6   5   4  3   2   1   The OH group tells us this is an alcohol.  Therefore, number the carbons starting from the end closest to the OH group.  The six carbon alkane is hexane, which will be changed to the alcohol name by dropping "e" and adding "ol" giving "hexanol."  Since the OH group is attached to carbon #1, this is 1-hexanol.  Lastly, prefix this name with the names of the other groups attached to the main chain, in alphabetical order with their positions given.  In this case there is only one group (we still call the bromine atom a "group") called the bromo group, attached to carbon #4.  Therefore the complete name is 4-bromo-1-hexanol.   Steve
