IMF Questions

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules due to fluctuations in electron distribution.

Front

Which molecule has only London dispersion forces?

Back

I2 (Iodine) has only London dispersion forces.

Front

What type of intermolecular force is present in water?

Back

Hydrogen bonding is the primary intermolecular force in water.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces that occur between molecules, affecting physical properties like boiling and melting points.

Front

What type of intermolecular forces does NH3 (Ammonia) exhibit?

Back

NH3 exhibits hydrogen bonding, dipole-dipole interactions, and London dispersion forces.

Front

How do London dispersion forces vary with molecular size?

Back

London dispersion forces are stronger in larger, heavier atoms or molecules due to increased polarizability.

Front

Which molecule has the strongest London dispersion forces: F2, Br2, I2, or Cl2?

Back

I2 (Iodine) has the strongest London dispersion forces among these options.

Front

What is the difference between dipole-dipole forces and hydrogen bonding?

Back

Dipole-dipole forces occur between polar molecules, while hydrogen bonding is a specific, stronger type of dipole-dipole interaction involving hydrogen bonded to highly electronegative atoms like N, O, or F.

Front

What is a dipole moment?

Back

A dipole moment is a measure of the separation of positive and negative charges in a molecule, indicating its polarity.

Front

What is the significance of hydrogen bonding in biological systems?

Back

Hydrogen bonding is crucial for the structure and function of biomolecules, such as DNA and proteins, influencing their stability and interactions.
