Why does hydrogen bonding exists between water molecules but not between hydrogen sulfide molecules?
Hydrogen bonding in water molecules exists due to the large electronegativity difference between hydrogen and oxygen, allowing a strong dipole-dipole interaction. Hydrogen sulfide lacks this strong electronegativity difference between hydrogen and sulfur, resulting in weaker van der Waals forces instead of hydrogen bonding.
What type of attraction occurs between nonpolar covalent molecules?
Van der Waals forces, specifically London dispersion forces, are the primary type of attraction that occurs between nonpolar covalent molecules. These forces result from temporary fluctuations in electron distribution within the molecules, leading to weak attractions between them.
What is the force that exits between two molecules?
The force that exists between two molecules is typically called intermolecular forces. These forces can include van der Waals forces, hydrogen bonding, or electrostatic interactions. The strength of these forces can vary depending on the molecules involved and their structure.
The forces between SO2 molecules are known as?
van der Waals forces.
What is the weakest chemical bond?
Hydrogen bonding. Perhaps Van der Waal's forces could be included as weak bonds.

Why is dioxygen a gas and sulphur a solid?
oxygen is a gas because it is held together by weak van der waals forces acting between the small molecules sulfur usually forms s8 molecules so the van der waals forces acting between the molecules are lager giving it a higher boiling point

Such properties of oxygen as its appearance and freezing point are determined by?
The appearance of oxygen is a colorless and odorless gas. Its freezing point is -218.79°C (-361.82°F). These properties are determined by the molecular structure of oxygen, which exists as diatomic molecules (O2) that have weak van der Waals forces between them.
The forces between SO2 molecules are known as?
van der Waals forces.
What do van der waals do?
they form temporary, weak dipole attractions between molecules
Why boiling point of nitrogen is less than oxygen although it forms more covalent bonds?
The boiling point of nitrogen is lower than oxygen because nitrogen molecules are smaller and lighter, so they experience weaker van der Waals forces of attraction between molecules. Oxygen molecules are larger and heavier, leading to stronger van der Waals forces, thus requiring more energy to break apart and boil.
What is the weakest chemical bond?
Hydrogen bonding. Perhaps Van der Waal's forces could be included as weak bonds.
Which kind of bonds are the weakest kind?
The Van der Waals forces are the weakest bond type. They include attractions and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces. They are names after Dutch scientist Johannes Diderik van der Waals.
What type of attractive forces are being overcome when liquid oxygen boils at 90 K?
Van der Waals forces between oxygen molecules are being overcome when liquid oxygen boils into a gas at 90 K. These forces include London dispersion forces and dipole-dipole interactions.
. Hydrogen bonds and van der Waals forces are types of?
intermolecular forces that are responsible for holding molecules together in substances. Hydrogen bonds occur between molecules with hydrogen atoms bonded to electronegative atoms like oxygen or nitrogen, while van der Waals forces are weaker interactions resulting from temporary fluctuations in electron distribution.
