Question

boiling point of water is 373 K than boiling point of H2S is
less than 300 K
more than 300 K but less than 373 K
more than 300
more than 373 k​

Answer 1

The boiling point of water is 373K Than the boiling point of H₂S is ...

1. less than 300K
2. more than 300K but less than 373K
3. more than 300K
4. more than 373K

solution : we know when F, O or N atoms are attached to hydrogens atoms, hydrogen bond will appear due to high electronegativity difference between them.

chemical formula of water is H₂O so at room temperature, water molecules is found in liquid because of hydrogen bonding.

but compound H₂S is found in gas because Sulphur atoms don't show hydrogen bond.

now you know as well, a gas has very low boiling point compare to liquid.

Therefore the boiling point of H₂S should be less than 300K.

Therefore the correct option is (1).
