Solution: Ethylene glycol (HOCH2CH2OH) and pentane (C5H12) are both liquids at room temperature and room pressure, and have about the same molecular weight.One of these liquids has a much lower normal boiling

Problem

Ethylene glycol (HOCH2CH2OH) and pentane (C5H12) are both liquids at room temperature and room pressure, and have about the same molecular weight.

One of these liquids has a much lower normal boiling point (36.1 oC) compared to the other one (198 oC). Which liquid has the lower normal boiling point?
