The alkanes are a homologous series of compounds containing only carbon and hydrogen that have the general formula . Members of this series include butane (), 2,2-dimethylpentane (), hexane (), and heptane (). The boiling points of some members of this homologous series are shown. Using their condensed structural formulas, match the compound with the most likely boiling point.

Question

Rank from highest to lowest boiling point.
2,2-dimethylpentane () <---- Highest Boiling Point
heptane ()
hexane ()
butane () <---- Lowest Boiling Point

Answer 1

I believe heptane has the highest b.p. followed by 2,2-dimethylpentane, followed by hexane and butane.

Answer 2

In order from highest to lowest.

heptane, 2,2-dimethylpentane, hexane, and butane .
