CHXI09:HYDROGEN

The low density of ice compared to water is due to
1 Hydrogen bonding interactions
2 Dipole - dipole interactions
3 Dipole - induced dipole interactions
4 Induced dipole - induced dipole interactions
Explanation:
It is due to hydrogen bonding when \(\mathrm{\mathrm{H}_{2} \mathrm{O}}\) forms a cage like structure in solid ice and density reduced.

Two ice cubes are pressed over each other until they unite to form one block. Which one of the following forces dominates for holding them together?
1 Dipole-dipole interaction
2 Van der waals' forces
3 Hydrogen bond formation
4 Covalent attraction
Explanation:
It is due to H - bonding.
CHXI09:HYDROGEN

When two ice cubes are pressed over each other, they unite to form one cube. Which of the following forces is responsible to hold them together?
1 Hydrogen bond formation
2 Dative bond formation
3 Covalent attraction
4 Ionic interaction
Explanation:
Two ice cubes stick to each other due to H-bonding.

The M.P of most the solid substances increase with an increase of Pressure. However ice melts at a temperature lower than its usual melting point when pressure is increased. This is because
1 Ice is less denser than \(\mathrm{\mathrm{H}_{2} \mathrm{O}}\)
2 Pressure generates heat
3 The chemical bonds break under pressure
4 Ice is not a true solid
Explanation:
Ice occupy more volume than liquid water \(\mathrm{(}\) Ice \(\mathrm{\rightleftharpoons}\) water \(\mathrm{)}\). Increase of pressure favours forward reaction (Le-Chatelier's principle).
