If the boiling point of


If the boiling point of $\mathrm{H}_{2} \mathrm{O}$ is $373 \mathrm{~K}$, the boiling point of $\mathrm{H}_{2} \mathrm{~S}$ will be :

  1.  less than $300 \mathrm{~K}$

  2. equal to $373 \mathrm{~K}$

  3. more than $373 \mathrm{~K}$

  4. greater than $300 \mathrm{~K}$ but less than $373 \mathrm{~K}$

Correct Option: 1


At room temperature, water is liquid and has boiling point $373 \mathrm{~K}$ due to hydrogen bonding. Whereas $\mathrm{H}_{2} \mathrm{~S}$ is a gas and it has no hydrogen bonding. Hence boiling point of $\mathrm{H}_{2} \mathrm{~S}$ is less than $300 \mathrm{~K}$ (boiling point of $\mathrm{H}_{2} \mathrm{~S}$ is $-60^{\circ} \mathrm{C}$ ).
