Intermolecular Forces

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

Hydrogen bonding.

Front

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

Back

Dispersion forces.

Front

What is the primary intermolecular force in HCl?

Back

Dipole-dipole forces.

Front

Which molecules exhibit hydrogen bonding?

Back

Molecules containing N-H, O-H, or F-H bonds.

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.

Front

What factors affect the strength of intermolecular forces?

Back

Factors include molecular size, shape, and polarity.

Front

What is a characteristic of 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

Do nonpolar molecules have intermolecular forces?

Back

Yes, nonpolar molecules experience dispersion forces.

Front

What is the significance of intermolecular forces in liquids?

Back

Intermolecular forces determine the properties of liquids, such as viscosity and surface tension.
