How to name hydrocarbons
IUPAC Rules
1) Determine the continous chain atoms
longest of carbon
Eg cccc
These are
· both
the
longest chains in the formula
This will defirmine the base name 4 :
Butane
eg
2)
Any chain branching off is called
CH3
an
alky/ group
Eg
Che CH2 Cha CH2 CH-tThis would be called
·
Methyl
would
~ Ethyl look like e
CHz-CH2-PH-CHz
CHy CH2
3) The final name of a branch is based on the position
amount of
and the
alkyl groups present
Always number from the end that has the closest alky
zi
group
ey
-
end of the chain
This is called
:
2-methylhexane
