Alkali halides do not show dislocation defect because
- A anions cannot be accommodated in vacant spaces
- B cations and anions have almost equal size
- C there is large difference in size of cations and anions
- D cations and anions have low coordination number
Answer & Solution
Correct Answer
(B) cations and anions have almost equal size
Step-by-step Solution
Detailed explanation
Generally in alkali halides, cations and anions have almost equal size, thus they do not show dislocation defect.
