Naming Organic Compounds

1. Organic Chemistry
MUST : Draw full structural formulae of :-
2-methyl hexane
2,4-diethyl nonane
3-chloro-octanoic acid
SHOULD : Identify where name is NOT in agreement with
IUPAC rules 
COULD : Draw the repeat unit of the condensation polymer
formed from benzene-1,4-dicarboxylic acid and 1.6-
diaminohexane.

2. Aims
• Understand what is meant by a homologous
series.
• Distinguish between empirical, structural and
molecular formulae.
• Deduce structural isomers up to C6.

3. Homologous Series

4. Gradation of Physical Properties

5. Empirical Molecular Structural
• Empirical Formula of a compound shows the
ratio of elements present in a compound.
• Molecular Formula of a compound shows
how many atoms of each element are present
in a molecule of the compound.
• Structural Formula shows every atom and
bond.

• HL How many isomers are there of Heptane ?
– Name them 
