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.

The answer to your question is below

Explanation:

Alkane                      Formula                    Boiling point (°C)

Methane                   CH₄                                     -162

Ethane                      CH₃CH₃                               - 89

Propane                    CH₃CH₂CH₃                        - 42

Butane                      CH₃(CH₂)₂CH₃                     - 0.5

Pentane                    CH₃(CH₂)₃CH₃                      36

Hexane                     CH₃(CH₂)₄CH₃                      69

Heptane                    CH₃(CH₂)₅CH₃                      98

Octane                      CH₃(CH₂)₆CH₃                     126

Nonane                     CH₃(CH₂)₇CH₃                      151

Decane                      CH₃(CH₂)₈CH₃                     174

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
