Do strong intermolecular forces have positive numbers?
No, strong intermolecular forces typically have negative values when expressed numerically in terms of energy or potential energy. The more negative the value, the stronger the intermolecular forces.
Are intermolecular forces of attraction strong?
the strength depends on the molecule in question, but they are strong
How do intermolecular forces determine a substance's state?
Intermolecular forces determine a substance's state by influencing the attractions and interactions between its particles. A substance with strong intermolecular forces, such as hydrogen bonding, tends to be solid or liquid at room temperature. Weak intermolecular forces, like London dispersion forces, make a substance more likely to be a gas.
Why are hydrogen bonds the strongest of the intermolecular forces?
Hydrogen bonds are the strongest intermolecular forces because they involve a hydrogen atom bonded to a highly electronegative element (such as oxygen or nitrogen). This creates a large electronegativity difference that leads to a strong attraction between the hydrogen atom and an electronegative atom on another molecule.
Explain why oil does not dissolve in water.?
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
What does a strong odor indicate about the strength of intermolecular forces in a compound and why?
A strong odor typically indicates that the compound has weak intermolecular forces. This is because substances with weak intermolecular forces tend to easily vaporize and disperse in the air, allowing their molecules to reach our nose more easily and produce a noticeable smell. Conversely, compounds with strong intermolecular forces tend to have lower vapor pressures and are less likely to produce a strong odor.
Do strong intermolecular forces have positive numbers?
No, strong intermolecular forces typically have negative values when expressed numerically in terms of energy or potential energy. The more negative the value, the stronger the intermolecular forces.
Are intermolecular forces of attraction strong?
the strength depends on the molecule in question, but they are strong
What is a sentence for intermolecular force?
Intermolecular forces shown by the dotted lines not by strong covalent bonds.
Why liquids have a definite volume but no shape?
The intermolecular forces are not sufficiently strong.
How do intermolecular forces determine a substance's state?
Intermolecular forces determine a substance's state by influencing the attractions and interactions between its particles. A substance with strong intermolecular forces, such as hydrogen bonding, tends to be solid or liquid at room temperature. Weak intermolecular forces, like London dispersion forces, make a substance more likely to be a gas.
What is the correct order of states from least to greatest intermolecular forces of attraction?
The correct order is: gas < liquid < solid. This is because in the gas phase, molecules are far apart and have weak intermolecular forces, in the liquid phase, molecules are closer together with moderate intermolecular forces, and in the solid phase, molecules are tightly packed with strong intermolecular forces.
Why are hydrogen bonds the strongest of the intermolecular forces?
Hydrogen bonds are the strongest intermolecular forces because they involve a hydrogen atom bonded to a highly electronegative element (such as oxygen or nitrogen). This creates a large electronegativity difference that leads to a strong attraction between the hydrogen atom and an electronegative atom on another molecule.

Water and oil have different strengths of intermolecular bonds so don't mix.
Does intermolecular force change from solid to liquid or liquid to gas?
Yes, the intermolecular forces generally change as a substance transitions from solid to liquid to gas. In solid form, molecules are held together by strong intermolecular forces. In liquid form, these forces weaken to allow molecules to move more freely. In gas form, intermolecular forces are weakest as molecules are far apart and move independently.
Process of vaporization require an input of energy?
Yes, the process of vaporization does require an input of energy. The energy is required to break the intermolecular forces of a given substance. The intermolecular forces is usually very strong.
How melting and boiling points are affected by intermolecular forces?
Melting and boiling points are higher when intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces) are stronger. These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.
