Question

$FeS{O}_4\bullet 7H_{2}O$ (Green vitriol) represents which type of crystal system?

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

Answer 1

The correct option is C Monoclinic

For $FeS{O}_4\bullet 7H_{2}O$
$a\ne b\ne c$ and $\alpha =\gamma ={90}^{\circ }$ and $\beta ={90}^{\circ }$
Hence, it belongs to Monoclinic system
