Question

Monoclinic sulphur is an example of monoclinic crystal system. What are the characteristics of the crystal system?

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

Answer 1

Answer: (D)

For monoclinic crystal system,
$a\neq b\neq c,\alpha =\gamma =90^\circ ,\beta \neq 90^\circ $
