Interpretation: The alkane molecules octane,
Concept introduction: A liquid only bolls once its vapor pressure equals atmospheric pressure. This is directly dependent upon intermolecular forces. If the latter are large in magnitude the temperature is attained at high values. Thus, higher order
In general the alkanes that are branched appear to be spherical, as a result of less surface area show smaller boiling points. For higher alkanes, the greeter size amounts to greeter surface are4s and thus high values of boiling points. For example
