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
With the same anion, smaller the size of the cation, higher is the lattice energy. The correct order of size of cations is -
`Na^(+) lt K^(+) lt Rb^(+) lt Cs^(+)`
Hence, the lattice energy of `NaF` will be maximum i.e., `NaF.`
