Free Crystalline Solids MCQs with Answers
184 Crystalline Solids MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.

Correct answer: Allotropy184. In crystalline structure, when the length of all axes and angles are unequal then crystal will be.
- A. Cubic
- B. Monoclinic
- C. Orthorhombic
- D. Triclinic
Explanation: In crystallography, the crystal system is determined by the lengths of the axes and the angles between them.
