Consider the Born- Haber cycle for the formation of an ionic compound given below and identify the compound (Z) formed.

Options

A. MX
B. `M^(+) X_((g))^(-)`
C. `M^(+) X_((s))^(-)`
D. `M^(-) X_((s))^(-)`

Answer

C

Explanation

The energy released when the requisite numbers of positive and negative ions are condensed into crystal to form one mole of the compound is called lattice energy
`M_((g))^(+) + X_((g))^(-) overset(Delta H_(5))rarr underset((Z))(MX_((x))), Delta H_(5) rarr` Lattice energy.
