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 ° . 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 ≠ c and α = γ = 90 ° ≠ β are parameters of monoclinic unit cell.
