How do ionic and molecular compounds differ in physical properties?
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
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.
What are some properties that would help distinguish a ionic compound from a molecular compound?
Ionic compounds typically have higher melting and boiling points compared to molecular compounds, due to the strong electrostatic forces between ions in the crystal lattice. Ionic compounds also tend to conduct electricity when dissolved in water or in molten state, while molecular compounds do not conduct electricity in either state. Additionally, ionic compounds are often composed of a metal and a nonmetal, whereas molecular compounds are composed of nonmetals.
What accounts for the observed differences in the properties of ionic and molecular compounds?
t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
Describe properties that would help you to distinguish an ionic compound from a molecular compound.?
Ionic compounds typically have higher melting and boiling points compared to molecular compounds due to the strong electrostatic forces between oppositely charged ions. Ionic compounds are typically soluble in water and conduct electricity when dissolved or in molten state, whereas molecular compounds are often insoluble in water and do not conduct electricity in any state.
How are the properties of molecular compounds different from those of ionic cmpounds?
Molecular (covalent) compounds are not dissociated in water.

Is a brittle compound a molecular compound?
No, a brittle compound does not necessarily indicate it is a molecular compound. Brittle compounds can be either molecular or ionic, depending on their chemical bonding. Brittle molecular compounds typically have covalent bonds, while brittle ionic compounds have ionic bonds.

How can molecular compounds be distinguished from ionic compounds?
Many ionic compounds exist as crystals but covalent compounds as molecules (there are exceptions as diamond though). Ionic compounds would be good electrical conductors unlike molecular compounds.
How can water dissolve some ionic compounds as well as some molecular compounds?
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.
What phenomenon about ionic compounds helps to explain many of these properties related to the molecules?
Opposites attract
What are the difference in conductivity between ionic and molecular compounds?
Ionic compounds typically have higher conductivity than molecular compounds because ionic compounds dissociate into ions in solution, allowing for the flow of electric current. Molecular compounds, on the other hand, do not dissociate into ions in solution and therefore exhibit lower conductivity.
Do molecular compounds boil at a higher temperature than ionic compounds?
No
