Dipole-dipole forces.

Front

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

Back

London Dispersion Forces.

Front

What intermolecular force is present in CO₂?

Back

London Dispersion Force.

Front

Define dipole-dipole forces.

Back

Intermolecular forces that occur between polar molecules due to the attraction between the positive end of one molecule and the negative end of another.

Front

What are London Dispersion Forces?

Back

Weak intermolecular forces arising from temporary dipoles in molecules, present in all molecules but significant in nonpolar ones.

Front

What is hydrogen bonding?

Back

A strong type of dipole-dipole interaction that occurs between molecules containing hydrogen bonded to highly electronegative atoms like N, O, or F.

Front

How do intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points due to the increased energy required to separate molecules.

Front

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

Back

Larger molecules have more electrons and a greater polarizability, leading to stronger London Dispersion Forces.

Front

What is the significance of intermolecular forces in biological systems?

Back

Intermolecular forces are crucial for the structure and function of biomolecules, influencing properties like solubility and stability.

Front

How do dipole-dipole forces compare to London Dispersion Forces?

Back

Dipole-dipole forces are generally stronger than London Dispersion Forces due to the permanent dipoles in polar molecules.
