Question

For a crystal system $a=b=c$ and $\alpha =\beta =\gamma \ne {90}^o$, the structure is:

• A. tetragonal
• B. hexagonal
• C. rhombohedral
• D. monoclinic

Answer 1

Answer: (C)

rhombohedral

We have given from the question

$a=b=c$ & $\alpha =\beta =\gamma \ne {90}^{\circ }$

Form the given data

The given crystal system this condition is of rhombohedral.

Hence,

The option (C) is correct.
