An electrovalent compound is made up of

Assertion $(A)$: Higher lattice enthalpy leads to greater stability of ionic compounds.
Reason $(R)$: Lattice enthalpy is a direct measure of the electrostatic forces of repulsion among the constituent ions in an ionic solid.
The correct answer is

Given below are two statements:
Assertion $(A)$: Ionic compounds are formed by non-directional bonds.
Reasoning $(R)$: They are soluble in nonpolar solvents.
The correct answer is:

Consider the Born-Haber cycle for the formation of an ionic compound given below and identify the compound $Z$ formed.
$M_{(s)}$ $\xrightarrow{\Delta H_1} M_{(g)}$ $\xrightarrow{\Delta H_2} M^{+}_{(g)}$
$\frac{1}{2} X_{2(g)}$ $\xrightarrow{\Delta H_3} X_{(g)}$ $\xrightarrow{\Delta H_4} X^{-}_{(g)}$
$M^{+}_{(g)} + X^{-}_{(g)} \xrightarrow{\Delta H_5} Z$
