How to name and draw isomers of organic compounds

Definitions

Compounds of the same formula can have different arrangements of atoms (these are isomers).

Isomers: They have the same molecular formula but different structural formulas.

Organic compounds have chains and branches in the structural formula

Chains: The straight part of the structure

Branches: The parts that stem from the chains

Note:

How to name isomers

1. Find longest chain + name it (like a normal organic compound).
2. Name the branch (like a normal organic compound) + add “-yl” to the end.
3. Number the chain starting from the side closer to the branch
