NEET 2010 Chemistry question
Not in JEE Main or NEET syllabus
AB crystallizes in a body centred cubic lattice with edge length equal to . The distance between two oppositely charged ions in the lattice is:
Answer: (1)
Solution
In the bcc (CsCl-type) arrangement the ion at the body centre touches the oppositely charged ions at the corners, along the body diagonal. Body diagonal , and the centre-to-corner distance is half of it: \dfrac{\sqrt3 a}{2}\dfrac${1.732
