Which compound will show the highest lattice energy ?

A

KF

B

NaF

C

CsF

D

RbF

Text Solution

Verified by Experts

The correct Answer is:
B
For compounds containing cations of same charge, lattice energy increases as the size of the cation decreases. Thus, NaF has highest lattice energy. The size of cations is in the order `Na^(+) lt K^(+) lt Rb^(+) lt Cs^(+)`
