Water and Heavy water

Question

The high density of water compared to ice is due to

Easy

A

Hydrogen bonding interactions
B

Dipole – dipole interactions
C

Dipole – induced dipole interactions
D

Induced dipole-induced dipole interactions

Solution

Due to hydrogen bonding the ice has open cage like structure, therefore, in ice large gaps [empty space] are present, and hence ice molecules occupies more space as compared to liquid water.
$\large \therefore d_{ice} < d_{water[liquid]}$
$\large \because V_{ice} > V_{water}$
$\large \boxed {d \propto \frac{1}{V}}$
