Inter- & Intra- molecular forces Review

Front

What are intermolecular forces?

Back

Forces that occur between molecules, affecting their physical properties such as boiling and melting points.

Front

What are intramolecular forces?

Back

Forces that occur within a molecule, holding the atoms together, such as covalent and ionic bonds.

Front

Define dipole-dipole attraction.

Back

An intermolecular force that occurs between polar molecules, where positive and negative ends attract each other.

Front

What are London dispersion forces?

Back

Weak intermolecular forces that arise from temporary dipoles in nonpolar molecules.

Front

What type of intermolecular force is present in hydrogen chloride (HCl)?

Back

Dipole-dipole attraction.

Front

What is electronegativity?

Back

A measure of an atom's ability to attract and hold onto electrons.

Front

How do hydrogen bonds differ from other intermolecular forces?

Back

Hydrogen bonds are stronger than typical dipole-dipole interactions and occur specifically when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

What is the significance of covalent bonds in molecules?

Back

Covalent bonds are strong intramolecular forces that involve the sharing of electron pairs between atoms.

Front

What type of intermolecular force is present in noble gases?

Back

London dispersion forces.

Front

What is the role of ion-dipole forces?

Back

Ion-dipole forces occur between an ion and a polar molecule, important in solutions of ionic compounds.
