Assertion : Order of lattice energy for same halides are as \(\mathrm{LiF}>\mathrm{NaF}>\mathrm{KF}\). Reason : Size of alkali metals increases from Li to K.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Lattice energy is inversely proportional to the size of the cation. Therefore, due to the smallest cation \(\mathrm{Li}+, \mathrm{LiF}\) will have the highest lattice energy. So the option (1) is correct.

Assertion : Ionic compounds conduct electricity in solution as well as in molten form. Reason : Ionic compounds are formed by sharing of electrons.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Ionic compounds are formed by transfer of electrons. The formed cation and anion attract each other. In a solution or in the molten state, these ions separate, allowing them to conduct electricity. Hence the option (3) is correct.

The correct order of lattice energy of the following compounds
1 \({\rm{NaCl > MgB}}{{\rm{r}}_{\rm{2}}}{\rm{ > CaO > A}}{{\rm{l}}_{\rm{2}}}{{\rm{O}}_{\rm{3}}}\)
2 \({\rm{A}}{{\rm{l}}_{\rm{2}}}{{\rm{O}}_{\rm{3}}}{\rm{ > MgB}}{{\rm{r}}_{\rm{2}}}{\rm{ > CaO > NaCl}}\)

The magnitude of the lattice energy of a solid increases if
1 The ions are large
2 The ions are small
3 The ions are of equal size
4 Charges on the ions are small
Explanation:
Lattice energy is directly proportional to charge and inversely proportional to the size of the ion.

Assertion : Greater the lattice enthalpy, more stable is the ionic compound. Reason : The lattice enthalpy is greater for ions of higher charge and smaller radii .
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Stability of an ionic compound is stable because of the electrostatic attraction between its positive and negative ions. The lattice energy \(o\) is a measure of strength of this attraction. Higher lattice energy implies stronger ionic compound.Lattice energy increases for ions with higher charges and shorter distances between ions. So the option (2) is correct.
