The boiling points of compounds can be determined by considering the strength of the intermolecular forces between molecules. Compounds with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher boiling points. Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.

How can one determine whether a compound is ionic or molecular?
One can determine whether a compound is ionic or molecular by looking at 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, conduct electricity when dissolved in water, and form crystal structures, whereas molecular compounds have lower melting and boiling points and do not conduct electricity in water.
How can one determine the substance with the highest boiling point in a given set of compounds?
To determine the substance with the highest boiling point in a set of compounds, you need to compare their molecular structures and intermolecular forces. The substance with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, will typically have a higher boiling point. Additionally, larger molecules tend to have higher boiling points due to increased surface area for intermolecular interactions.
How are ionic and covalent compounds different in terms of melting and boiling point and electrical conductivity and hardness and brittleness?
Ionic compounds generally have higher melting and boiling points.
Why do the melting and boiling points of a particular subsatnce vary?
It is because the intermolecular forces(the attractive forces between the molecules of a substance) differ from one substance to another. The chemical with the stronger intermolecular forces will have higher melting and boiling points, and vice versa. This is because more energy is required to separate the molecules to melt or boil the substance, if the forces are strong. The factors that determine the size of these forces are :the type of bonding in the molcules, andthe mass of the molecules.
Write down the differences between ionic compound from covalent compounds?
Ionic Compounds are formed by complete transfer of electrons while Covalent compounds are formed by sharing of electrons. Ionic compounds have higher melting points while covalent compounds have lower.

Write down the differences between ionic compound from covalent compounds?
Ionic Compounds are formed by complete transfer of electrons while Covalent compounds are formed by sharing of electrons. Ionic compounds have higher melting points while covalent compounds have lower.
How are molecular compounds different from an ionic compound?
Molecular compounds consist of covalent bonds formed by sharing electrons between atoms, while ionic compounds involve the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions. Molecular compounds typically have lower melting and boiling points compared to ionic compounds and are often composed of nonmetals. Ionic compounds tend to have higher melting and boiling points, are composed of metals and nonmetals, and form crystalline lattices.
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.
Could you compare and contrast simple from steam distillation in terms of type of mixtures separated?
Simple and steam distillation are similar in that they use boiling to separate organic components. Simple distillation boils them off at their boiling points, then condenses them. Steam distillation uses water mixed with the compounds to lower their boiling points and avoid decomposing them by heat.
What are some properties of molecular compounds?
Simple molecular structures like H2O and CO2 have the following properties: 1) Physical state: usually liquids and gases at room temperature due to weak intermolecular forces 2) Melting and boiling points: low (below 2000 C) melting and boiling points due to weak intermolecular forces 3) Electrical conductivity: cannot conduct electricity because there are no free electrons 4) Solubility: insoluble in water, but soluble in organic substances such as petrol Macromolecular structures such as diamond and SiO2 have the following properties: 1) Physical state: hard solids at room temperature due to the many strong covalent bonds holding the atoms together 2) Melting and boiling points: high melting and boiling points due to the many strong covalent bonds that must be broken before the substance can change state 3) Electrical conductivity: cannot conduct electricity because there are no free electrons 4) Solubility: insoluble
Which compound is predicted to have the highest boiling point?
The compound with the highest boiling point will have the strongest intermolecular forces, such as hydrogen bonding or ion-dipole interactions, which require more energy to break. Examples of compounds with high boiling points include water (due to hydrogen bonding) and ionic compounds like sodium chloride (due to strong ion-dipole interactions).
What are two physical characteristics of ionic compounds What is one chemical characteristics of ionic compounds?
Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions. Ionic compounds have high melting and boiling points, again due to strong forces of attraction between the ions. Ionic compounds dissolve easily in water.
Distillation works when the components of a solution have a different?
Boiling points. As the solution is heated, the component with the lower boiling point evaporates first. The vapor is then cooled and condensed back into a liquid, resulting in the separation of the original components.
