Question:

Which of the following contains only one Bravais lattice?

Options:

Hexagonal

Cubic

Tetragonal

Monoclinic

Correct Answer:

Hexagonal

Explanation:

The correct answer is option 1. Hexagonal

Crystal system	Edge lengths	Angles	Bravais Lattices
Cubic	a = b = c	α = β = γ = 90°	Simple, body centred, face centred
Tetragonal	a = b ≠ c	α = β = γ = 90°	Simple, body centred
Orthorhombic	a ≠ b ≠ c	α = β = γ = 90°	Simple, body centred, face centred, end face centred
Monoclinic	a ≠ b ≠ c	α = γ = 90° β ≠ 90°	Simple, end face centred
Hexagonal	a = b ≠ c	α = β = 90° γ = 120°	Simple
Rhombohedral	a = b = c	α = β = γ ≠ 90°	Simple
Triclinic	a ≠ b ≠ c	α ≠ β ≠ γ ≠ 90°	Simple
