Honors Intermolecular Forces

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It is an important factor in determining the type of bond that will form between atoms.

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces that occur between molecules, influencing their physical properties such as boiling and melting points.

Front

What type of intermolecular force is present in ammonia (NH3)?

Back

Ammonia (NH3) exhibits hydrogen bonding as its primary intermolecular force.

Front

In a nonpolar covalent bond, how do electrons behave?

Back

In a nonpolar covalent bond, electrons are shared equally between the atoms involved.

Front

In a polar covalent bond, how do electrons behave?

Back

In a polar covalent bond, electrons are attracted more towards the atom with the greater electronegativity.

Front

What is the London Dispersion Force?

Back

London Dispersion Forces are weak intermolecular forces that arise from temporary dipoles in molecules, occurring in all types of molecules.

Front

What is dipole-dipole interaction?

Back

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

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 nitrogen, oxygen, or fluorine.

Front

How does the strength of intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points, as more energy is required to separate the molecules.

Front

What is the relationship between molecular size and London Dispersion Forces?

Back

As molecular size increases, London Dispersion Forces also increase due to a larger electron cloud, leading to greater polarizability.
