Question

What is the best explanation for the observation that h2o is a liquid at room temperature and h2s is a gas at room temperature? quizlit?

Answer 1

h2O there is strong hydrogen bonds, dipole dipole forces of attraction and dispersion forces of attraction which requires alot of energy to overcome
while in h2S , only dipole dipole and dispersion are present, which requires lesser force to overcome hence h2s has lower bp hence gas at room temp
