JEE · NEET Previous Year Question

$The correct option for axial distances and axial angles for hexagonal crystal system is$

Topic: JEE PYQ

Answer: C. Full step-by-step solution below.

A $a \neq = b \neq = c, α \neq = β \neq = γ = 90^{\circ}$
B $a = b \neq = c, α = β = γ = 90^{\circ}$
C $a = b \neq = c, α = β = 90^{\circ}, γ = 120^{\circ}$
D $a \neq = b \neq = c, α = β = γ = 90^{\circ}$

Correct answer: C

Solution

(c) For hexagonal crystal system; axial distance = a = b \neq = c axial angles = α = β = 90^{\circ}, γ = 120^{\circ}
