Question

Nitrogen and water are both covalent compounds but nitrogen is a gas and water is a liquid at room temperature. Explain liquid

Answer 1

This is because, H₂O has intermolecular hydrogen bond between it's molecule (H-O-H------H-O-H) while H₂S has weak Van Der Wals forces between it's molecule.Hence the molecules of H₂O are strongly packed than H₂S,thus water is at liquid state at room temperature.
