1.	H2O is liquid and H2S is a gas because.(a) oxygen forms stronger hydrogen level than sulphur. (b) oxygen is less electronegative than sulphur. (c) atomic radius of oxygen is less than that of sulphur. (d) atomic radius of oxygen is greater than that of sulphur
Answer» (a) oxygen forms stronger hydrogen level than sulphur. Explanation: H₂O has intermolecular hydrogen bond between its molecules (H—O—H------H—O—H) while H₂S has weak Van der Waals forces between it's molecules. Hence the molecules of H₂O are strongly packed than H₂S, thus water is at liquid state at room temperature.
