Question
The normal boiling points of ammonia, water, and hydrogen fluoride increase in the order NH3 (bp = –33 °C) < HF (bp = 19 °C) < H2O (bp = 100 °C). What is the best explanation for this ordering?
A.✓ Correct
H2O forms a greater number of hydrogen bonds per mol than NH3 or HF.
B.
H2O forms stronger hydrogen bonds than NH3 or HF.
C.
H2O has a larger dipole moment than NH3 or HF.
D.
H2O has stronger London dispersion forces than NH3 or HF.
