Multiple choice

Which of the following matches of ‘lattice system: edge lengths and axial angles’ is not correct?

  1. Cubic : a = b = c and α = β = γ = 90o

  2. Tetragonal : a = b ≠ c and α = β = γ = 90˚

  3. Orthorhombic : a ≠ b ≠ c and α = β = γ = 90˚

  4. Rhombohedral : a = b = c and α = β = γ ≠ 90˚

  5. Monoclinic : a ≠ b ≠ c and α ≠ β ≠ γ ≠ 90˚

E Correct answer
Explanation

This option is correct because 'lattice system: edge lengths and axial angles in Monoclinic is a ≠ b ≠ c and α = γ = 90˚, β ≠ 90˚ respectively. in Triclinic, the 'lattice system: edge lengths and axial angles is a ≠ b ≠ c and α ≠ β ≠ γ ≠ 90˚
