A solid A B has NaCl structure. If the radius of cation A⁺ is 170 pm , then the maximum possible radius of the anion B⁻ is
Options
- A397.4 pm
- B347.9 pm
- C210.9 pm
- D410.6 pm
Correct answer
D. 410.6 pm
Step-by-step solution
For NaCl type structure r_ A⁺ r_ B⁻ =0.414-0.737 For maximum possible radius of B⁻ aligned & r_ A⁺ r_ B⁻ =0.414, 170 r_ B⁻ =0.414 & r_ B⁻ = 170 0.414 =410.6 pm aligned
