Question

For the maximum ionic character during bond formation, the low charge on cation and a low charge anion are required.

• A. True
• B. False

Answer 1

The correct option is A True

This is according to Fajan's rules.

• Cation should have low charge ${(Na}^{+}>{Mg}^{+2})$
• Anion should have low charge $(O^{-2}>{CO}^{-})$ as $-2$ is less than $-1$
