Final answer:
The correct name for the compound Ca(ClO₂)₂ is calcium chlorite, as it contains the chlorite ion (ClO₂^-).
Step-by-step explanation:
The correct name for the compound Ca(ClO₂)₂ is calcium chlorite. Option a, calcium chloride, would have been correct if the formula were CaCl₂. Option b, calcium chloroxide, is not a conventional name for any calcium compound. Option c, calcium chlorite, is the correct name because the ClO₂^- ion is called chlorite ion. Finally, option d, calcium chlorate, would be incorrect because the formula for calcium chlorate is Ca(ClO₃)₂, where the ion has one more oxygen atom.
