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

A

MX

B

`M^(+) X_((g))^(-)`

C

`M^(+) X_((s))^(-)`

D

`M^(-) X_((s))^(-)`

Text Solution

Verified by Experts

The correct Answer is:
C
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.
