Which solid will have the weakest intermolecular force?
1 Sodium fluoride
2 Naphthalene
3 Ice
4 Phosphorous
Explanation:
Ice has the lowest melting point out of the given solids, hence it has the weakest intermolecular forces.

Which among the following solid is a non-polar solid?
1 Hydrogen chloride
2 Carbon dioxide
3 Water
4 Carbon dioxide
Explanation:
Carbon dioxide is a non-polar solid because the bonds are linear and dipole moment points in opposite directions. This linear configuration cancel out the dipole moments, leaving a net polarity of zero HCl is a polar molecule. \(\mathrm{H}_{2} \mathrm{O}\) is also polar in nature. Similarly, \(\mathrm{SO}_{2}\) is also polar in nature.

Under which category iodine crystals are placed among the following?
1 Molecular crystal
2 Covalent crystal
3 Metallic crystal
4 Ionic crystal
Explanation:
Iodine crystals are molecular crystals, in which constituent particles are molecules having interparticle forces are van der Waal's forces.

Which of the following statements is not correct about molecular crystals?
1 They are generally soft and easily compressible
2 They have low melting and boiling points
3 They consist of polar or non-polar molecules
4 They are good conductors of electricity as the electrons are delocalised in the bonds
Explanation:
Molecular solids are insulators.
