The parameters of the unit cell of a substance are a=2.5,b=3.0,c=4.0,α=90°,β=120°γ=90°.a = 2 . 5, b = 3 . 0, c = 4 . 0, \alpha = 90 ° , \beta = 120 ° \gamma = 90 ° . The crystal system of the substance is :

Options

  1. AHexagonal
  2. BOrthorhombic
  3. CMonoclinic
  4. DTriclinic

Correct answer

C. Monoclinic

Step-by-step solution

a≠b≠ca \ne b \ne c and α=γ=90°≠β\alpha = \gamma = 90 ° \ne \beta are parameters of monoclinic unit cell.
