Intermolecular Forces

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces that exist between molecules.

Front

What are intramolecular forces?

Back

Intramolecular forces are the forces that exist within a molecule.

Front

Which property from the Periodic Table helps determine the type of intermolecular force?

Back

Electronegativity is used to determine the type of intermolecular force.

Front

What type of intermolecular force is present in HCl?

Back

The intermolecular force present in HCl is dipole-dipole.

Front

What type of intermolecular force is present in I2, Br2, and Cl2?

Back

The intermolecular force present in I2, Br2, and Cl2 is dispersion.

Front

Define dipole-dipole forces.

Back

Dipole-dipole forces are attractions between the positive end of one polar molecule and the negative end of another polar molecule.

Front

What are dispersion forces?

Back

Dispersion forces, also known as London dispersion forces, are weak attractions that occur due to temporary dipoles in nonpolar molecules.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

How does electronegativity affect intermolecular forces?

Back

Higher electronegativity differences between atoms in a molecule lead to stronger dipole-dipole interactions and hydrogen bonds.

Front

What is the relationship between molecular size and dispersion forces?

Back

Larger molecules have stronger dispersion forces due to increased polarizability.
