In crystals which one of the following ionic compounds would you expect maximum distance
between centres of cations and anions?
A.
$$LiF$$
B.
$$CsF$$
C.
$$CsI$$
D.
$$LiI$$
Answer :
$$CsI$$
Solution :
As $$C{s^ + }\,ion$$ has larger size than $$L{i^ + }$$ and $${I^ - }$$ has larger size than $${F^ - },$$ therefore maximum distance between centres of cations and anions is in $$CsI.$$
