Question

Which of the following crystal system will exhibit the geometry of a match box?

• A. Cubic
• B. Orthorhombic
• C. Triclinic
• D. Monoclinic

Answer 1

The correct option is B Orthorhombic

For a match box, all the three edges are of different lengths and all the three axial angles are same and equal to ${90}^o$
$\therefore$
$a\ne b\ne c$ and $\alpha =\beta =\gamma ={90}^o$
These are the parameters of an orthorombic crystals.


Examples of orthorobic crystals are rhombic sulphur, $KN{O}_3$ and $BaS{O}_4$.
