Propane (molar mass 44.11 g/mol) boils at-421°C Ethanol has almost the same mola

Question

Propane (molar mass 44.11 g/mol) boils at-421°C Ethanol has almost the same molar mass (4607 g/mol, but boils at 78.5? which of the following BEST explains the reason for the large discrepancy in boiling point? Choose one: O A. Propane is ionic and, therefore, has a lower boiling point. B. Ethanol is ionic and, therefore, has a higher boiling point C. Both compounds only exhibit van der Waals forces. D. Both compounds are polar. Ethanol is more polar than Propane. E. Ethanol exhibits hydrogen bonding. F. Propane exhibits hydrogen bonding.

Explanation / Answer

E, Ethanol exhibits hydrogen bonding.

Whereas, propane doesnot exhibit hydrogen bonding. Thus, Ehanol boils at higher temperature than propane.
