Lattice energy (numerical value) of chloride of alkali metals is in order of

A

`LiCl gt NaCl gt KCl gt RbCl gt CsCl`

B

`LiCl lt NaCl lt KCl lt RbCl lt CsCl`

C

`NaCl lt KCl lt LiCl lt RbCl lt CsCl`

D

`NaCl lt KC lt RbCl lt CsCl lt Li Cl`

Text Solution

Verified by Experts

The correct Answer is:
A
The correct order for lattice enregy of chloride of alkali metals
`LiCl gt NaCl gt KCl gt RbCl gt CsCl`
Smaller cation polarises anion to a greater extent hence, larger covalent nature and thus higher lattice energy.
