Chemical Bonding and Molecular Structure - Result Question 20
####20. The low density of ice compared to water is due to
[1997]
(a) hydrogen-bonding interactions
(b) dipole-dipole interactions
(c) dipole-induced dipole interactions
(d) induced dipole-induced dipole interactions
Show Answer
Solution:
- (a) We know that due to polar nature, water molecules are held together by intermolecular hydrogen bonds. The structure of ice is open with large number of vacant spaces, therefore the density of ice is less than water.
