Question

Which of the following is not involved in born haber cycle?
1. Sublimation energy
2. Ionisation energy
3.lattice energy
4. Electronegativity

Answer 1

Electronegativity is not involved in the Born-Haber cycle. (option 4)

• Born-Haber's cycle is used to determine lattice energy which cannot be measured directly it requires a stepwise determination of the lattice energy.
• Crystal and electron energy can be calculated using  Born-Haber's cycle but not electronegativity.
• Born-Haber's cycle is defined as the cycle of change in enthalpy of a process that gives details about lattice energy and shows us the formation of a solid crystalline ionic compound from atoms in their standard state.
• Electronegativity cannot be found using Born-Haber's cycle.

Answer 2

(4)-ELCTRONEGATIVITY
