At 1 atm, which proposed increasing boiling-point order is FALSE? The choices compare the named pure substances, not aqueous solutions.

Solution:
Water boils above both methanol and ethanol because of its extensive hydrogen-bond network. The correct order for those three is CH₃OH < C₂H₅OH < H₂O. Increasing dispersion explains A and C; hydrogen bonding places HF above HBr and HI in B.
