. 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.
B: 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
Best Answer
Explanation:-
- Crystalline solids have a regular arrangement of its constituent particles over a long range in a crystal lattice
due to which there are regularities in structure and they have sharp melting points.
Final Answer:-
The correct option is (B) a regular arrangement of constituent particles observed over a long range in crystal lattice
