CHXII01:THE SOLID STATE

318961 Among the following statements, one that is wrong about Zinc blende type structure is

1 Each \(\mathrm{Zn}^{2+}\) ion is surrounded tetrahedrally by four \(S^{2-}\) ions by four \(\mathrm{Zn}^{2+}\) ions.
2 \(S^{2-}\) ions form fcc arrangement.
3 \(\mathrm{AgBr}\) has Zinc blende type structure.
4 Cuprous halides have Zinc blende type structure.
CHXII01:THE SOLID STATE

318962 \(\mathrm{CsBr}\) crystallises in a body centred cubic lattice. The net cell length is \(436.6 \mathrm{pm}\). Given that the atomic mass of \(\mathrm{Cs}=133 \mathrm{amu}\) and that of \(\mathrm{Br}=\) 80 amu and Avogadro number being \(6.02 \times 10^{23} \mathrm{~mol}^{1}\), the density of \(\mathrm{CsBr}\) is

1 \(8.25 \mathrm{~g} / \mathrm{cm}^{3}\)
2 \(4.25 \mathrm{~g} / \mathrm{cm}^{3}\)
3 \(42.5 \mathrm{~g} / \mathrm{cm}^{3}\)
4 \(0.425 \mathrm{~g} / \mathrm{cm}^{3}\)
