Nomenclature
What do you notice about these
molecules?
How about these molecules?
So how can we name molecules so we
know the locations of the side chains
and the double/triple bonds?
Naming Rules
1.
Count the longest chain
of consecutive carbons.
2.
Use the appropriate prefix
and suffix to name the
longest chain (same as
before)
3.
Number the carbons so
the double/triple bonds
or side groups have the
lowest number
 Example:
Naming Rules Continued
4. Write the number of the
carbon the double or
triple bond begins on in
front of the name
 Example:

Naming Rules Continued
5. If there is a side chain:
- follow the same naming
rules
-then name the side chain
by writing the number of
the carbon it is located on
- count the number of
carbons in the side chain
- use the appropriate prefix
for the side chains and add
the ending -yl

Naming Rules Continued
6. If there is more than one
side chain, the side group
names must be written in
alphabetical order
 Example:

Naming Rules Continued
6. If there are multiples of the
same side group, it needs
to be denoted using a
prefix
