Question

The strongest bond is
a)Na-Cl b)cs-cl c) Both a&b d)none​

Answer 1

Answer:

The correct option is: none of these or NaCl

Explanation:

According to Fajan rules, ionic character increases with increase in size of the cation (Cs > Rb > K > Na) and with decrease in size of the anion (F > Cl > Br > I). Thus, CsF has higher ionic character than NaCl and hence bond in CsF is stronger than in NaCl.
