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

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.
