In sodium chloride crystal, the number of next nearest neighbours of each Na + ion is 12 Na + ions.
Diamond follows ZnS structure and the number of carbon atoms per unit cell is 8 .
When AgCl is dopped with CdCl 2 , the number of cation vacancies is equal to number of cadmium ions that get inducted.
Crystals having F - centres are paramagnetic and not diamagnetic.

From among the following, the incorrect statement isa)In sodium chlori...
Incorrect Statement Explanation:

a) In sodium chloride crystal:
- In a sodium chloride crystal, each Na+ ion is surrounded by 6 Cl- ions as nearest neighbors.
- The number of next nearest neighbors of each Na+ ion is 6 and not 12.

b) Diamond structure:
- Diamond follows a diamond cubic structure and not ZnS structure.
- The number of carbon atoms per unit cell in a diamond cubic structure is 8.

c) Doping of AgCl with CdCl2:
- When AgCl is doped with CdCl2, the number of cation vacancies is not equal to the number of cadmium ions that get inducted.
- The number of cation vacancies may differ from the number of doping ions depending on the doping concentration.

d) Metal excess defect with F-centres:
- In the case of a metal excess defect with F-centers, the crystal is paramagnetic and not diamagnetic.
- F-centers are responsible for the paramagnetic behavior due to unpaired electrons.
Therefore, the incorrect statement among the given options is option 'D' where it states that the crystal is diamagnetic in the case of a metal excess defect with F-centers.
