Chemical Bonding And Molecular Structure Ques 14
14. Among the following which compound will show the highest lattice energy?
[1993]
(a) $KF$
(b) $NaF$
(c) $CsF$
(d) $RbF$
Show Answer
Answer:
Correct Answer: 14.(b)
Solution:
(b) For compounds containing ions of same charge, lattice energy increases as the size the ions decrease. Thus, $NaF$ has highest lattice energy. The size of cation is in the order $Na^{+}<$ $K^{+}<Rb^{+}<Cs^{+}$.
