[edit] Branched Alkanes

Rule #1: Modifiers are separated from the main branch using a pipeline character | and follow the same rules as mentioned earlier for methane and ethane.

Rule #2: For modifiers, if the superscript to the right is 1, it is omitted.

Rule #3: As your name adds atoms, tag the atoms (1,2,3,4...) as you go, including not only carbon but all atoms except hydrogen.

Rule #4: For modifiers, a subscript at the left of the C (or other symbol, to be discussed later) represents the atom #.

[edit] Similar Branches

Rule #5: Similar branches can be named by listing their positions as subscripts before the center symbol (C), separated by commas (if two such groups come from the same, list them repetitively.)

[edit] Multiple Branches

Rule #6: In deciding which modifier comes first, larger branches and groups have higher priorities.

Rule #7: Treat each modifier the same: precede each modifier with a pipeline and place in order.

[edit] Nested Branches

Rule #8: Nested branches are also modifiers and should be treated as primary branches.
