Molecular compounds have relatively high boiling points?
Molecular compounds typically have lower boiling points compared to ionic compounds because of weaker intermolecular forces between molecules. The boiling points of molecular compounds increase with increasing molecular size and polarity. However, they generally have lower boiling points compared to ionic compounds due to the nature of the forces holding the molecules together.
Why does 0.300 M KCl have a higher boiling point that 0.500 M glucose?
KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds.
How do you differentiate simple molecular compounds and giant molecular compounds?
Simple molecular compounds have discrete molecules held together by weak intermolecular forces, while giant molecular compounds have repeating units bonded together by strong covalent bonds. Simple molecular compounds typically have low melting and boiling points and are often gases or liquids at room temperature, while giant molecular compounds tend to have high melting and boiling points and are usually solids at room temperature.
Molecular compounds boil at much higher temperatures than do ionic compounds true or false?
This is false. Ionic compounds have higher boiling points than molecular compounds. For example, the boiling point of the ionic compounds copper(II) oxide, CuO, and sodium chloride, NaCl are 2,000 degrees C and 1,413 degrees C, respectively. The boiling point of the molecular compounds carbon tetrachloride, CCl4, and water, H2O are 76.72 degrees C and 100 degrees C, respectively.
List properties common to many organic compounds?
Some common properties of organic compounds include having covalent bonds, containing carbon and hydrogen atoms, being flammable, having low melting and boiling points, and often having a complex molecular structure.

How are the melting points and the boiling points of molecular compounds different from ionic compounds?
Ionic bonds are significantly resistant to heat, while molecular bonds are broken more easily with the addition of heat energy. Due to this, ionic compounds have much higher boiling points than molecular substances in most cases.
How are the properties of molecular compounds poor conducters of electricity?
Because have lower melting points and boiling points
How are the melting points and boiling point of molecular compounds different from ionic compounds?
Molecular compounds typically have lower melting points and boiling points compared to ionic compounds. This is because molecular compounds are held together by weaker intermolecular forces (such as Van der Waals forces) compared to the strong electrostatic interactions in ionic compounds.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
How can you determine whether a compound is ionic or molecular?
You can determine whether a compound is ionic or molecular based on the types of elements it contains. Ionic compounds typically consist of a metal and a nonmetal, while molecular compounds are made up of nonmetals only. Additionally, ionic compounds tend to have high melting and boiling points, while molecular compounds have lower melting and boiling points.

Why do molecular compounds have low melting points and low boiling points relative ionic substances?
The bonds in the molecule are weaker.
What are two major characteristics of molecular compounds?
Low melting and boiling points. Some are polar and some are nonpolar. Those that are polar will dissolve in water. They also do not conduct electricity.
What causes the differences in melting points and boiling points between ionic and covalent compounds molecular substances?
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic compounds.
What accounts for the observed differences in ionic and molecular compounds properties?
The differences in properties between ionic and molecular compounds are primarily due to the nature of their chemical bonding. Ionic compounds have strong electrostatic attractions between oppositely charged ions, leading to high melting and boiling points, as well as conductivity in solution. In contrast, molecular compounds have weaker intermolecular forces, resulting in lower melting and boiling points, and most are not conductive in solution.
