1. Organic compounds Compounds that contain a chain of car-
bon atoms
2. Number of electrons in carbons outer shell 4 so can form 4 covalent bonds
3. Carbon-Carbon bonds are... non-polar and relatively strong
4. Empirical formula the simplest whole number ratio of
atoms of each element in a compound
5. molecular formula a formula that tells us the actual number
of atoms of each different element in a
compound
6. structural formula a way of writing the formulas of an
organic compound in which bonds
aren't shown but each carbon is written
seperately.
7. skeletal formula a way of showing the structure of a
complex molecule. only labels the car-
bon and side groups.
8. nomenculture the universl rules about naming com-
pounds
9. why use nomenculture? so all scientists use the same names
and others can understand what com-
pounds they have used.
10. IUPAC ruling system the way that the IUPAC has developed
a naming convention that chemists all
follow.

11. side chains are shown by... a prefix of the root of the longest carbon
chain in the side chain.
12. Alkanes general formula CnH2n+2
13. Alkene FG C=C double bond anywhere
14. alcohol FG -OH at end or on a branch
15. Aldehydes FG - CHO at the end of the chain
16. ketones FG - CO - carbonyl group in the middle of
the chain
17. Carboxylic acids FG - COOH terminates the chain
18. Esthers FG - COO - in the middle
19. Nitriles FG C triple bonded to N terminates the
chain
20. Alkynes FG C triple bonded to C
21. Homologous series a family of organic compounds with
the same functional group, but different
carbon chain length.
22. Similar rules of homologous series? have the same general formula and
their formula will differ from the next
member of the series.
23. Isomers molecules with the same molecular for-
mula but different arrangements of
their atoms.
