In NaCl the nearest neighbour distance of ions is
a) a/4
b) a(3)1/2/2
c) a/2
d) a(2)1/2/2
Dear Student,
NaCl has a face centered cubic(fcc) structure.
Each Na+ ion has 6 Cl- ions as neighbours and each Cl- ion has 6 Na+ ions as neighbours.
Thus, the coordination number of NaCl is 6.
The nearest neighbout distance is .
The correct answer is option (c).
Hope it helps.
