These notes were the ones I had compiled over the course of my A Levels, which took my grade from a B to consistently above 90%, including in my actual A Level in which I achieved 289/300 (96.3%), so I know these contain all the information you could possibly need to achieve a high score in the act...

, Introduction to organic chemistry (3.1)
Nomenclature (3.1.1)
- Organic compounds can be represented by:
o Empirical formula – the simplest possible whole number ratio of the different types of
atoms within the compound
o Molecular formula – formula that gives the actual number of atoms of each element in one
molecule
o General formula – shows the number of atoms of each element in a substance which has n
carbon atoms. All the molecules in a homologous series have the same general formula
o Structural formula – shows how the atoms are joined together in a molecule
o Displayed formula – shows all the bonds and atoms in a molecule
o Skeletal formula – uses lines to represent bonds. Each point represents a C atom
- Homologous series = a family of compounds with same general formula and similar chemical
properties
o Characteristics:
• Same general formula
• Same functional group
• Similar chemical properties
- Functional group: nomenclature guidelines:
Functional group Prefix Suffix
Alkane -ane
Alkene -ene
Halogenoalkane Fluoro- / Bromo- /
Chloro- / Iodo-
Alcohol Hydroxy- -ol
Aldehyde -al
Ketone Oxo- -one
Carboxylic acid -oic acid
Nitrile -nitrile
Amine Amino- -amine
Acyl chloride -oyl chloride
Acid anhydride -oic anhydride
Ester -oate
Amide -amide
- Naming priorities:
carboxylic acids > aldehydes > ketones > alcohols > alkenes > halogenoalkanes
