Solution

The correct option is D 2×(rNa++rCl)
  • One face of NaCl crystal lattice looks like,
  • Na+ ions are situated at the centre of every edge in octahedral voids.
  • The minimum distance between two Na+ ions is AC
(AC)2=(AB)2+(BC)2
d=2(rCl+rNa+)
The minimum distance between two Na+ ions which are present along the edges is 2×(rNa++rCl).
