Boiling point dependence on enthalpy

A fluid has a boiling temp. T = 300 K at p = 1 atm; $\Delta h_{vap}$ = 10 kcal/mol. Suppose you make a molecular modification of the fluid that adds a hydrogen bond so that the new enthalpy is 15 kcal/mol at p = 1 atm. What is the new boiling temperature?

I think I'm supposed to use the Clausius-Clapeyron equation, but it takes me nowhere so far.
