The boiling points for a set of compounds in a homologous series can be qualitatively predicted using intermolecular force strengths. Using their condensed structural formulas, rank the homologous series for a set of alkanes by their boiling point Rank from highest to lowest boiling point. To rank items as equivalent, overlap them.

The decreasing order for the boiling point will be: CH3CH2CH2CH2CH2CH2CH3 > CH3CH2CCH2CH3CH3 > CH3CH2CH2CH2CH2CH3CH3 > CH3CH2CH2CH3

What is meant by boiling points?

Boiling point can be described as the temperature that is responsible for the conversion of liquid state to vapor state. The boiling point is dependent on the molar mass and branching. As all are alkanes, the force is the same.

As Heptane is the straight hydrocarbon has highest boiling point.

3,3-dimethylpentane has 7 carbon chained branched hydrocarbon, therefore, boiling point increased.

Hexane is straight hydrocarbon but has a low molecular weight, so the boiling point increased further.

As butane has 4 carbon straight chains, therefore it has the lowest boiling point.
