Question

Choose the correct option
Which of the given og tions is NOT a form of real number?​

Answer 1

Answer:

C

When coordination number is eight, the r  

+

/r  

−

 ratio lies between 0.225 to 0.414

A) Radius ratio increases from 0.155-1 as coordination no. increases.

B) The difference in the size of ions increases as coordination number increases that is why in the CsCl structure having high coordination no. of 8, the size of the cation and anion is almost similar.

C) When radius ratio lies between 0.225 to 0.414 then coordination number is 4. Coordination no. is 8 when the radius ration is 0.732-1.

D) Statement is correct.

Option C is the correct answ
