Why is the boiling point of water greater than hydrogen sulfide?
The boiling point of a substance is determined by the strength of the intermolecular forces between its molecules. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point in water.
What is an attraction between molecules of the same substance and why?
An attraction between molecules of the same substance is called cohesion. This occurs because molecules of the same substance have similar properties and are able to bond together through intermolecular forces such as hydrogen bonding or van der Waals forces. Cohesion is responsible for many properties of substances, such as surface tension in water.
Are hydrogen bonds an example of cohesion?
Yes, hydrogen bonds are an example of cohesion. Cohesion refers to the attraction between molecules of the same substance, and hydrogen bonds form between water molecules due to the positive and negative charges on the hydrogen and oxygen atoms. This cohesion is responsible for the surface tension and high boiling point of water.
What is a attraction between molecules of the same substance?
This is called an intermolecular force. It may be a van der Waals force, dipole-dipole attraction or a hydrogen bond.
Which two molecules choose to be partners in a hydrogen bond between water molecules?
The two molecules that choose to be partners in a hydrogen bond between water molecules are the oxygen atom of one water molecule and a hydrogen atom of another water molecule.
What interferes with hydrogen bonding between water molecules?
Substances that disrupt hydrogen bonding between water molecules include solutes like salts, acids, and bases, as well as nonpolar substances like oil. These substances can prevent water molecules from forming hydrogen bonds with each other by either competing for hydrogen bond formation or interfering with the water molecules' ability to interact.
Consider a substance that is made of molecules that are stable when dry in the presence of water the molecules separate what type of chemical bond holds the substance together when dry?
The substance is likely held together by hydrogen bonds when dry. Hydrogen bonding occurs between hydrogen atoms of one molecule and electronegative atoms (like oxygen or nitrogen) of another molecule, creating a weak attraction between the molecules.

How do bonds form between water molecules?
The bond between water molecules is known as a hydrogen bond.

This cohesion is responsible for the surface tension and high boiling point of water.
Is hydrogen the strongest bond that forms between molecules?
No Hydrogen is the weakest bond that can possible form between two molecules.
What is a attraction between molecules of the same substance?
This is called an intermolecular force. It may be a van der Waals force, dipole-dipole attraction or a hydrogen bond.
What name is given to the bond between water molecules?
The bond between water molecules is called the hydrogen bond.
Which two molecules choose to be partners in a hydrogen bond between water molecules?
The two molecules that choose to be partners in a hydrogen bond between water molecules are the oxygen atom of one water molecule and a hydrogen atom of another water molecule.
What is the name of the gap between the molecules in a substance?
The gap between molecules in a substance is known as intermolecular space. This space varies depending on the substance and affects the physical properties of the material.
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.
