Question

Which of the following is true for a monoclinic system:

• A. $a\ne b\ne c,\alpha =\gamma ={90}^{\circ },\beta \ne {90}^{\circ }$
• B. $a\ne b\ne c,\alpha \ne \beta \ne \gamma \ne {90}^{\circ }$
• C. $a=b=c,\alpha \ne \beta \ne \gamma \ne {90}^{\circ }$
• D. $a=b=c,\alpha =\beta =\gamma \ne {90}^{\circ }$

Answer 1

The correct option is A $a\ne b\ne c,\alpha =\gamma ={90}^{\circ },\beta \ne {90}^{\circ }$

For a monoclinic system : $a\ne b\ne c,\alpha =\gamma ={90}^{\circ },\beta \ne {90}^{\circ }$
