Which of the following statements are CORRECT? I. Ionic compounds have high melting and boiling points. II. Carbon compounds are a poor conductor of electricity. III. Carbon compounds have low melting and boiling point.

Which of the following statements are CORRECT? I. Ionic compounds have high melting and boiling points. II. Carbon compounds are a poor conductor of electricity. III. Carbon compounds have low melting and boiling point. Correct Answer All statements are correct.

Explanation:

  • Ionic bonds are very strong and a lot of energy is needed to break them. So ionic compounds have high melting and boiling points.
  • Carbon compounds don't have a free electron that is required for electricity transfer thus making them bad conductors.
  • Carbon compounds consist of molecules in which the atoms are joined by strong covalent bonds. However, the molecules in the compounds are held together by weak forces so these substances have low melting and boiling points.
