Ionic compounds are formed most easily with
1 low electron affinity, high ionisation energy
2 high electron affinity, low ionisation energy
3 low electron affinity, low ionisation energy
4 high electron affinity, high ionisation energy
Explanation:
Formation of ionic bond is favoured by (I) low ionisation potential of metal. (II) greater value of electron affinity of non-metal. (III) higher value of lattice energy of resulting ionic compound

Assertion : The crystal structure gets stabilised even though the sum of electron gain enthalpy and ionisation enthalpy is positive. Reason : Energy is absorbed during the formation of crystal lattice.
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:
Energy is released during the formation of a crystal lattice, and this energy serves as a qualitative measure of the stability of an ionic compound. So the option (3) is correct.

The electronegativities of two elements are 0.7 and 3.0. The bond formed between them would be
1 Ionic
2 Covalent
3 Co-ordinate covalent
4 Metallic
Explanation:
The electronegativity difference between two elements = 3 - 0.7 = 2.3 If the E.N. difference is \({\rm{ > 1}}{\rm{.7}}\) then the bond formed is ionic.
