ethanol has a normal boiling point of 78.3 C. Why is the normal boiling point higher than methanol but lower than iso-propanol listed above?

ethanol has a normal boiling point of 78.3 C. Why is the normal boiling point higher than methanol but lower than iso-propanol listed above? normal bpt iso-pronanol is 82.3 delat H 45.4. Would you expect the heat of vap of ethanol to follow the same trend explain?
