A) The units of surface tension are dynes \[c{{m}^{-1}}\]
B) The units of viscosity coefficient of a liquid are "poise"
C) \[\text{CsCl}\]crystallizes in body centred cubic type of lattice
D) The coordination number of \[{{\text{S}}^{2-}}\]in ZnS is 6
Correct Answer: D
Solution :
Zinc blende \[(ZnS)\] has \[\text{ccp}\]arrangement of \[{{S}^{2-}}\] and\[\text{Z}{{\text{n}}^{\text{2+}}}\] in alternative'tetrahedral sites. The coordination number of \[\text{Z}{{\text{n}}^{\text{2+}}}=4\] and \[{{S}^{2-}}=4\] in ZnS.
