Lattice energy is directly proportional to charge. More charge more LE ....Alcl3 > Mgcl2 >Nacl ( charge Al+3 > Mg+2 >Na+1 )

Alcl3>Mgcl2>Nacl because lattice energy directly proportional to charge on the cation. Since charge of Al is +3,Mg is +2 & Na is +1,so,the order of lattice energy is Alcl3>Mgcl2>Nacl.
