AB crystallises in a body-centred cubic ...

AB crystallises in a body-centred cubic lattice with edge length 'a' equal to 387 pm. The distance between two oppositely charged ions in the lattice is

A

335 pm

B

250 pm

C

200 pm

D

300 pm

Text Solution

Verified by Experts

The correct Answer is:
A
For a bcc lattice, `2(r_(+) + r_(-)) = sqrt3a`
where `r_+` = radius of cation
`r_-` = radius of anion
a = edge length
`:. (r_+ + r_-) = (sqrt3xx387)/2 = 335.142 pm ~~335` pm
