intermolecular forces 1

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, which arise from the unequal sharing of electrons between atoms.

Front

Which molecule is an example of a polar molecule?

Back

H₂O (water) is an example of a polar molecule.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions).

Front

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

Back

Hydrogen bonding is the type of intermolecular force present in NH₃.

Front

What are London Dispersion Forces (LDF)?

Back

London Dispersion Forces are weak intermolecular forces that arise from temporary dipoles in molecules.

Front

How do London Dispersion Forces affect noble gases?

Back

An increase in London Dispersion Forces makes it more difficult to separate noble gases and increases their boiling points.

Front

Which noble gas has the highest boiling point?

Back

Xe (xenon) has the highest boiling point among noble gases.

Front

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

Back

Dispersion forces are present in I₂, Br₂, and Cl₂.

Front

What is hydrogen bonding?

Back

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

Front

What is the difference between dipole-dipole forces and dispersion forces?

Back

Dipole-dipole forces occur between polar molecules, while dispersion forces occur between all molecules, regardless of polarity.
