|
|
structural fromula
|
shows:
kind number arrangement of atoms in a molecule |
|
|
saturated hydrocarbon
|
FILLED UP
if only has SINGLE bond& has the maximum numberof hydrogen atoms possible on its chains |
|
|
unsaturated hydrocarbon
|
it hasDOUBLE or TRIPLE bonds
fewer hydrogen bonds for each carbon atom than a saturated hydrocarbon |
|
|
Isomer
|
same chemical formula but
different chemical structure * different substance with its own characteristics |
|
|
subsituted hydrocarbon
