Question

If $a,b,c$ represent cell dimensions and $\alpha ,\beta ,\gamma$ represents crystal angles then, the crystal system $a\ne b\ne c,\alpha =\gamma ={90}^{\circ },\beta \ne {90}^{\circ }$ belongs to:

• A. Tetragonal
• B. Triclinic
• C. Hexagonal
• D. Monoclinic

Answer 1

The correct option is D Monoclinic

The crystal system having $a\ne b\ne c,\alpha =\gamma ={90}^{\circ },\beta \ne {90}^{\circ }$ is a monoclinic system.
