Question

The correct order of the lattice energies of the following ionic compounds is (A) NaCl > MgBr2 > CaO > Al2O3 (B) NaCl > CaO > MgBr2 > Al2O3 (C) Al2O3 > MgBr2 > CaO > NaCl (D) MgBr2 > Al2O3 > CaO > NaCl

Lattice energy depends upon: (a) the product of ionic charges (b) the interionic distance ( c) nature of the crystaI structure Hence, more is the ionic charge, more will be the Iattice energy. So, the correct order is Al2O3 > CaO > MgBr2 > NaCl

Q. The correct order of the lattice energies of the following ionic compounds is

$N a Cl > M g B r_{2} > C a O > A l_{2} O_{3}$

$N a Cl > C a O > M g B r_{2} > A l_{2} O_{3}$

$A l_{2} O_{3} > M g B r_{2} > C a O > N a Cl$

$M g B r_{2} > A l_{2} O_{3} > C a O > N a Cl$

$A l_{2} O_{3} > C a O > M g B r_{2} > N a Cl$

Lattice energy depends upon :
(a) the product of ionic charges
(b) the interionic distance
( c) nature of the crystaI structure
Hence, more is the ionic charge, more will be the Iattice energy.
So, the correct order is
$A l_{2} O_{3} > C a O > M g B r_{2} > N a Cl$

Q. The correct order of the lattice energies of the following ionic compounds is

NaCl>MgBr2​>CaO>Al2​O3​

NaCl>CaO>MgBr2​>Al2​O3​

Al2​O3​>MgBr2​>CaO>NaCl

MgBr2​>Al2​O3​>CaO>NaCl

Al2​O3​>CaO>MgBr2​>NaCl
