The parameters of the unit cell of a substance are $a=2.5, b=3.0, c=4.0, \alpha=90^{\circ}, \beta=120^{\circ} \gamma=90^{\circ}$.
The crystal system of the substance is i.
Select the correct option:
A
Hexagonal
B
Orthorhombic
C
Monoclinic
D
Triclinic
✓ Correct! Well done.

Solution
$a \neq b \neq c$ and $\alpha=\gamma=90^{\circ} \neq \beta$
are parameters of monoclinic unit cell.
