Answer 2

Answer:

The correct increasing order of the strength of interparticle / intermolecular forces of the given three solids are as follows :

Y (300K) < Z (325K) < X (380K)

Explanation:

• At a standard pressure of 1 atmosphere, a compound's melting point is the temperature at which the solid phase changes to the liquid phase.
• Like solubility, density, colour, and electronegativity, a compound's melting point is a physical characteristic that can be used to identify it.
• The melting point of a compound is typically provided as a range since pinpointing the exact temperature at which a compound starts to melt is difficult.
• The temperature at which the first drops of liquid are noticed represents the lower end of the melting point range.
• The temperature at which all of the solid phase has changed to the liquid phase is the upper limit of the range.

Intermolecular Forces' Impact on Melting Points:

• The kind of intermolecular forces present inside the molecule has a significant impact on its melting point.
• The molecules of a compound exert intermolecular forces that are either attracting or repulsive.
• When a chemical is solid, its molecules form an ordered lattice structure due to their near proximity.
• Different intermolecular forces have varying degrees of attraction.
• As a result, compounds with hydrogen bonds require more energy to dispel molecular attraction than nonpolar compounds with merely London dispersion forces.
• As a result we can say that, the existence of hydrogen bonding raises a compound's melting point.

• In conclusion we can say that, more energy is required to stop the attraction between these molecules as the intermolecular forces become more powerful. Because of this, rising intermolecular forces are accompanied with rising melting points.
• Therefore, the increasing order of strength of intermolecular forces of the provided compounds are Y<Z<X.
