# In a monoclinic unit cell, the relation of sides

Question:

In a monoclinic unit cell, the relation of sides and angles are respectively

1. $a \neq b \neq c$ and $\alpha \neq \beta \neq \gamma \neq 90^{\circ}$

2. $\mathrm{a} \neq \mathrm{b} \neq \mathrm{c}$ and $\beta=\gamma=90^{\circ} \neq \alpha$

3. $\mathrm{a}=\mathrm{b} \neq \mathrm{c}$ and $\alpha=\beta=\gamma=90^{\circ}$

4. $a \neq b \neq c$ and $\alpha=\beta=\gamma=90^{\circ}$

Correct Option: , 2

Solution:
