H2S is far more volatile than water because :
A
Sulphur atom is more electronegative than oxygen atom.
B
Oxygen being more electronegative than sulphur forms hydrogen bond.
C
H2O has bond angle of nearly 1050.
D
Hydrogen atom is loosely bonded with sulphur.
Answer
Oxygen being more electronegative than sulphur forms hydrogen bond.
Explanation
Solution
As water has H-bonding due to the presence of highly electronegative oxygen but H2S does not (electronegativity of sulphur is low).
