Common
names for alkyl substituents
Certain
alkyl substituents are very common, and you should be able to recognise and
name them quickly, these are listed below.
In each case, the structural formula of the substituent is given where the C
that is attached to the rest of the molecule is in bold. A line drawing of a generic example and
the molecular models of the series of alkyl bromides are also available.
Notes:
- the the prefix iso is
not hyphenated.
- the symbol "R" is commonly used to generically represent
an alkyl group, e.g. R-X
