Which of the following is least ionic ?
- \( BaCl_2 \)
- AgCl
- KCl
- \( CoCl_2 \)
The Correct Option is B
Solution and Explanation
The order of ionic character among the compounds is:
\[\text{AgCl} < \text{CoCl}_2 < \text{BaCl}_2 < \text{KCl}\]
The reason is that \(\text{Ag}^+\) has a pseudo-inert gas configuration, making \(\text{AgCl}\) less ionic than the other compounds listed.
