(N/A) Water shows a high boiling point compared to hydrogen sulphide due to the high electronegativity of oxygen $(EN = 3.5)$. Water undergoes extensive $H$-bonding,as a result of which water exists as associated molecules.
To break these hydrogen bonds,a large amount of energy is required; so,the boiling point of $H_2O$ is high. In contrast,due to the lower electronegativity of $S$,hydrogen sulphide does not undergo hydrogen bonding. $H_2S$ exists as discrete molecules and hence its boiling point is much lower than that of $H_2O$. That is why $H_2S$ is a gas at room temperature.
