Chemical Bonding

The term used to refer to the bonds holding a molecule together is called intramolecular forces.
'Intra' in the context of intramolecular forces means within or inside, referring to the forces within a molecule.

Types of Bonding

The attractive force between atoms is known as a chemical bond.
Covalent bonding occurs via the sharing of electrons between atoms.

Hydrogen Bonding

The term for bonds occurring inside molecules is intramolecular bonds.
A molecule is a group of two or more atoms joined together via bonds.
To understand hydrogen bonding, one must first understand covalent bonding.
A hydrogen bond is a type of intermolecular force that arises between a hydrogen atom bonded to a highly electronegative atom and another electronegative atom.
Hydrogen can form a bond with electronegative atoms such as oxygen, nitrogen, and fluorine in a hydrogen bond.
When a chemical bond occurs between two atoms of different electronegativities, the bond is polar, resulting in a partial positive charge on the hydrogen atom.
Electronegativity plays a crucial role in hydrogen bonding, as it allows the formation of polar bonds and resulting partial charges.
A dipole is a molecule with a permanent electric dipole moment, which is important in hydrogen bonding as it allows for the attraction between partial charges.
For a molecule to serve as a hydrogen bond donor, it must have a hydrogen atom bonded to a highly electronegative atom.
A hydrogen bond acceptor is an electronegative atom that accepts the hydrogen bond, typically oxygen, nitrogen, or fluorine.
Hydrogen bonds are typically weaker than typical covalent bonds, but stronger than van der Waals forces.
