- Functional group is an alkane, therefore suffix = -ane
- The longest continuous chain is C5 therefore root = pent
- The branch is a C1 alkyl group i.e. a methyl group
- The first point of difference rule requires numbering from the right
as drawn, the substituent locant is 2-
2-methylpentane

- Functional group is an alkane, therefore suffix = -ane
- The longest continuous chain is C5 therefore root = hex
- There are two substitutents, both C1 alkyl group i.e. methyl groups
- The first point of difference rule requires numbering from the left
as drawn, the substituent locants are 3-
