Naming Alkanes
Alkanes are hydrocarbons with single bonds between the carbon atoms.
The general formula is CnH(2n + 2)
Alkanes and their Isomers
Isomers are compounds with the same molecular formula but different structural formula.
Isomers of Pentane: C5H12
n-pentane, methylbutane, dimethylpropane

Isomers of Hexane
n-hexane, 2-methypentane, 3-methypentane, 2,2-dimethybutane, 2,3-dimethybutane Questions
1. What is the key difference between the molecular and structural formula of a hydrocarbon?
2. Name and draw the isomers of C4H10.
3. Name and draw the isomers of C5H12.

  • Show Solutions for Questions 1 and 2
    1. The molecular formula shows how many of each type of atom are present in a molecule. The structural formula shows the connectivity of the atoms in the molecule - the bonds and the order in which the atoms are connected.
