Answer

Brief Explanations:

The boiling - point of straight - chain alkanes increases with an increase in the number of carbon atoms due to stronger London dispersion forces. We need to order the alkanes based on the number of carbon atoms from fewest to most. Ethane has 2 C atoms, pentane has 5 C atoms, heptane has 7 C atoms, and octane has 8 C atoms.

Answer:

ethane, pentane, heptane, octane
