Consider the Born-Haber cycle for the formation of an ionic compound, given below and identify the compound (Z) forme(d)

Options

  1. AM⁺ X⁻
  2. BM⁻ X⁻(s)
  3. CM X
  4. DM⁺ X⁻(g)

Correct answer

A. M⁺ X⁻

Step-by-step solution

The ionic compound formed is M⁺ X⁻(s) as the gaseous ions [M⁺(g) . and . Cl ⁻(g) ] combines in the crystal lattice which is in solid state.
