MHT CET 2026 Chemistry question

Which of the following is favourable condition for the formation of ionic bond?

(A)Low ionization enthalpy of metal and low negative value of electron gain enthalpy of non metal.
(B)Low ionization enthalpy of metal and high negative value of electron gain enthalpy of non metal.Correct
(C)High ionization enthalpy of metal and high negative value of electron gain enthalpy of non metal.
(D)High ionization enthalpy of metal and low negative value of electron gain enthalpy of non metal.

Answer: (B)

Solution

An ionic bond forms by transfer of electrons from a metal atom to a non-metal atom. The metal must lose electrons easily, so its ionization enthalpy should be low. The non-metal must accept electrons readily, so its electron gain enthalpy should be highly negative (large release of energy). Together with a high
