MCQ

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

A
a regular arrangement of constituent particles observed over a short distance in crystal lattice.
✓
a regular arrangement of constituent particles observed over a long distance in crystal lattice.
C
same arrangement of constituent particles in different direction
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 crystal lattice.

Crystals tend to have relatively sharp, well$-$defined melting points because all the component atoms, molecules, or ions are the same distance from the same number and type of neighbors; that is, the regularity of the crystalline lattice creates local environments that are the same.
