chain branching
When in a @C00960@ there is a net increase in the number of @C00949@ there is said to be chain branching. A simple example of a @C00959@ leading to chain branching is:
in which there is one @C00949@ (an oxygen atom) on the left and two chain carriers (a hydrogen atom and a hydroxyl radical) on the right.
