Page "Homo (disambiguation)" Paragraph 8

*" Homo -" prefix may be used in organic chemistry trivial names to indicate next higher straight chain homolog i. e. one noncyclic carbon more ( and similarly " dihomo -" meaning two noncyclic carbon more ), and is opposite of the prefix " Nor -" which usually means one noncyclic carbon less.

Unlike nor-homo generally talks about a straight chain homolog with rare exceptions.

Also unlike dinor, when the added carbons are not adjacent the term used may be bis homo instead of dihomo whereas dinor can refer to either removal of two adjacent or remote carbons.
