$HgS$

Vedclass · Answer

(D) The hexagonal crystal system is characterized by unit cell dimensions $a = b 
eq c$ and angles $\alpha = \beta = 90^{\circ}, \gamma = 120^{\circ}$.Graphite,Zinc oxide $(ZnO)$,and Cadmium sulfide $(CdS)$ (in its wurtzite form) crystallize in the hexagonal system.However,Mercury$(II)$ sulfide $(HgS)$,specifically in its cinnabar form,crystallizes in the trigonal (rhombohedral) crystal system.Therefore,$HgS$ does not have a hexagonal crystal system.
