Which of the following factor generally favours electrovalency? This question has multiple correct options
- A. Low charge on ions
- B. High charge on ions
- C. Large cation and small anion
- D. Small cation and large anion
Step-by-step solution
Electrovalency (ionic bond formation) is favored when the cation is large and the anion is small. According to Fajan's rules, a large cation has low polarizing power, and a small anion has low polarizability, which minimizes the covalent character and promotes ionic bonding.
