Question

Melting points of three solids X, Y and Z are 298 K, 314 K and 398 K respectively. Arrange these in increasing order of inter particle forces of attraction?

Answer 1

• Intermolecular forces are weaker attractions that hold molecules or noble gas particles close together when they are in a liquid or solid form.
• Intermolecular forces are the strongest in solids. "In solids, the intermolecular forces are very strong, and the constituent particles are closely packed, greater the melting point temperature of a solid, more is the magnitude of interparticle forces.
• Hence, The correct for increasing order of inter particle forces of attraction is X < Y < Z.
