Question

You are given the melting points of three unknown substances and are asked to predict which one is an ionic compound. You would select the compound with the _______ melting point.

Answer 1

The correct answer in the blank is highest melting point.

Step-by-step explanation:

• Ionic compounds have ionic compounds which are so strong that it needs a high amount of energy to breaking them.
• While covalent bonds are not so strong, so a less amount of energy is enough to break them.
• Hence element with high melting point will be ionic compound.

Answer 2

To identify which one is ionic compound, you would select the compound with the high melting point. Ionic compounds have high melting points because the electrostatic interactions that hold the compounds together are very strong. Hope this answers the question.
