Figure 1 shows the structural formulae of a molecule of butane and of a molecule of pentane, which are both components of various hydrocarbon fuel mixtures.
Figure 1
Butane and pentane are neighbouring members of the same homologous series.
Explain, using these formulae, why butane and pentane are neighbouring members of the same homologous series.
