At ordinary temperature H(_2)O is a liquid while H(_2)S is a gas. This is because H(_2)O has
-
A.
weak intermolecular forces holding its molecules together -
B.
strong hydrogen bonds holding its molecules together -
C.
induced dipole-induced dipole forces between its molecules -
D.
ionic force between its molecules
Correct Answer: Option B
Explanation
H(_2)O has stronger intermolecular dipole–dipole interaction because of the greater polarity (or a hydrogen bond). Because of the stronger intermolecular interaction H(_2)O is more stable and exists as a liquid.
