MCQ
Which of the following is least ionic?
- A$\mathrm{BaCl}_2$
- ✓$\mathrm{AgCl}$
- C$\mathrm{KCl}$
- D$\mathrm{CoCl}_2$
✓
Answer
Correct option: B.
$\mathrm{AgCl}$
b
$\mathrm{AgCl}<\mathrm{CoCl}_2<\mathrm{BaCl}_2<\mathrm{KCl}$ (ionic character)
$\mathrm{AgCl}<\mathrm{CoCl}_2<\mathrm{BaCl}_2<\mathrm{KCl}$ (ionic character)
Reason: $\mathrm{Ag}^{+}$has pseudo inert gas configuration.
