MCQ

The sharp melting point of crystalline solids is due to $.......$

A
A regular arrangement of constituent particles observed over a short distance in the crystal lattice.
✓
A regular arrangement of constituent particles observed over a long distance in the crystal lattice.
C
Same arrangement of constituent particles in different directions.
D
Different arrangement of constituent particles in different directions.

✓

Answer

Correct option: B.

A regular arrangement of constituent particles observed over a long distance in the crystal lattice.

A solid is said to be crystalline if the various constituent structural units $($atoms, ions or molecules$)$ of which the solid is made, are arranged in a definite geometrical pattern within the solid. The type of forces in crystalline solids are of long range order due to which they have sharp melting point.
