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