Which of the following has lower boiling point than dimethyl ether? Correct Answer Propane

The difference in molecular weight made difference between boiling point here mainly. It would be best to set up a better comparison and then ask the question. diethyl ether is a chain of 5 atoms in a row. The appropriate alkane to compare it to is pentane, also 5 atoms in a row. Ethane only has two carbons (CH3-CH3).
