Vedclass · Answer

(C) The formation of an ionic bond is favored by: $1$. Low ionization enthalpy of the metal (forming a cation). $2$. High electron gain enthalpy of the non-metal (forming an anion). $3$. High lattice energy,which is favored by small size and high charge on ions. Conversely,a large cation and a small anion do not favor the formation of an ionic bond because they lead to lower lattice energy and increased covalent character (Fajans' rule). Therefore,option $C$ is the correct answer.

Which of the following factors does not favor the formation of an electrovalent (ionic) bond?
