Weekly Quiz Competition

Question 1
4 / -1

Which of the following solids is the structure of CsCl crystal

A
Body centred cubic

B
Simple cubic

C
Face centred cubic

D
Edge centred cubic

Solution

CsCl has structure with Cl⁻ ions at the corners and Cs⁺ at the centre of the cube.
Question 2
4 / -1

Which of the following does not represent a type of crystal system

A
Triclinic

B
Monoclinic

C
Rhombohedral

D
Isotropical

Solution

Isotropical is not a crystal system.
Question 3
4 / -1

Which of the following primitive cells show the given parameters?
a ≠ b ≠ c, α = β = γ = 90^∘

A
Cubic

B
Tetragonal

C
Orthorhombic

D
Hexagonal

Solution

In orthorhombic crystal system, a ≠ b ≠ c but axial angles α, β and γ are equal and 90∘.
Question 4
4 / -1

Which of the crystal systems has more than one type of Bravais lattices?

A
Hexagonal

B
Rhombohedral

C
Triclinic

D
Monoclinic

Solution

Monoclinic has two Bravais lattices: Primitive and End centred.
Question 5
4 / -1

Monoclinic sulphur is an example of monoclinic crystal system. What are the characteristics of the crystal system?

A
a ≠ b ≠ c, α = β = γ = 90^∘

B
a ≠ b ≠ c, α ≠ β ≠ γ ≠ 90^∘

C
a = b ≠ c, α = β = γ = 90^∘

D
a ≠ b ≠ c, α = γ = 90^∘, β ≠ 90^∘

Solution

For a monoclinic crystal, the characteristics are:
a ≠ b ≠ c, α = γ = 90 & β ≠ 90.
So, correct answer is option D.
