Which compound will show the highest lattice energy ?

A

RbF

B

CsF

C

NaF

D

KF

Text Solution

Verified by Experts

The correct Answer is:
C

For the same anion `(F^(-))` lattice energy will be maximum for the smallest cation. The size of cations is in the order
`Na^(+) lt K^(+)lt Rb^(+)lt Cs^(+)`
Therefore maximum lattice energy is in NaF.
