Question

which property best indicates that a compound contains an ionic bond? it is insoluble in water. it can be easily flattened. it has a low boiling point. it conducts electricity when molten.

Explanation:

Ionic compounds dissociate into ions when molten, which allows them to conduct electricity. Many ionic compounds are soluble in water, they are brittle (not easily flattened), and have high boiling - points due to strong ionic bonds.

Answer:

It conducts electricity when molten.
