The incorrect order of lattice energy is :

Options

A. `AlF_(3) gt MgF_(2)`
B. `Li_(3)N gt Li_(2)O`
C. `NaCl gt LiF`
D. `TiC gt ScN`

Answer

C

Explanation

`LE prop (q^(+) * q^(-))/(r^(+)+r^(-))`
(a) `AlF_(3) gt MgF_(2)` [Charge on cation]
(b) `Li_(3)N gt Li_(2)O` [Charge on anion]
(c ) `NaCl gt LiF` [Size of cation and anion]
(d ) `TiC gt ScN` [Charge on cation and anion]
