Question

In a monoclinic unit cell, the relation of sides and angles are respectively : (A) a = b ≠ c and α = β = &gamma;= 90° (B) a ≠ b ≠ c and α = β = &gamma;= 90° ≠ α (C) a ≠ b ≠ c and β = &gamma;= 90° ≠ α (D) a ≠ b ≠ c and α ≠ β ≠&gamma;≠ 90°

Monoclinic crystal is one of the 7 crystal system. In monoclinic system, the crystal is describe by vectors of unequal lengths, So, we have a ≠ b ≠ c and β=&gamma;=90° ≠ α

Q. In a monoclinic unit cell, the relation of sides and angles are respectively :

$a = b \neq = c$ and $α = β = γ = 9 0^{\circ}$

$a \neq = b \neq = c$ and $α = β = γ = 9 0^{\circ} \neq = α$

$a \neq = b \neq = c$ and $β = γ = 9 0^{\circ} \neq = α$

$a \neq = b \neq = c$ and $α \neq = β \neq = γ \neq = 9 0^{\circ}$

Monoclinic crystal is one of the $7$ crystal system. In monoclinic system, the crystal is describe by vectors of unequal lengths,
So, we have $a \neq = b \neq = c$ and $β = γ = 9 0^{\circ} \neq = α$

Q. In a monoclinic unit cell, the relation of sides and angles are respectively :

a=b=c and α=β=γ=90∘

a=b=c and α=β=γ=90∘=α

a=b=c and β=γ=90∘=α

a=b=c and α=β=γ=90∘

Monoclinic crystal is one of the 7 crystal system. In monoclinic system, the crystal is describe by vectors of unequal lengths, So, we have a=b=c and β=γ=90∘=α

$a = b \neq = c$ and $α = β = γ = 9 0^{\circ}$

$a \neq = b \neq = c$ and $α = β = γ = 9 0^{\circ} \neq = α$

$a \neq = b \neq = c$ and $β = γ = 9 0^{\circ} \neq = α$

$a \neq = b \neq = c$ and $α \neq = β \neq = γ \neq = 9 0^{\circ}$

Monoclinic crystal is one of the $7$ crystal system. In monoclinic system, the crystal is describe by vectors of unequal lengths,
So, we have $a \neq = b \neq = c$ and $β = γ = 9 0^{\circ} \neq = α$
