Question

Among the following, which compound will show the highest lattice energy?

• A. $KF$
• B. $NaF$
• C. $CsF$
• D. $RbF$

Answer 1

The correct option is B $NaF$

For compounds containing ions of same charge, lattice energy increases as the size of ions decreases. Thus, $NaF$ has highest lattice energy.
