The fourth co-ordination number of Cl ⁻ ion is CsCl is x whereas fourth co-ordination number of Cl ⁻ ion in NaCl is y . What is the value of x+y ?

Correct answer

Step-by-step solution

CsCl has BCC like structure. The 4^ th co-ordination number of Cl ⁻ ion is 24 x=24 NaCl has FCC structure . The 4^ th co-ordination number of Cl ⁻ ion is 6 aligned & y=6 & x+y=24+6=30 aligned
