Clarifying Questions: 1. Why do solid covalent compounds ( molecules) have low melting points?
2. Why do solid ionic compounds (ions) have high melting points ?
3. How are carbon tetrachloride and sodium chloride different from each other?
Please help ASAP

Explanation:

1. Covalent compounds have low melting points because the attraction of each molecule is easy to overcome

2. Ionic compounds have high melting points and boiling points because the electrostatic forces of attraction between oppositely charged ions are strong and large amount of energy is require to separate the ions.

3. Carbon tetrachloride is insoluble in water and behaves as a bad conductor of electricity while sodium chloride is soluble in water and behave as a good conductor of electricity in their aqueous state

since electrons are negative the answer is neagtaive
