Intermolecular forces review

Front

What is hydrogen bonding?

Back

A strong type of dipole-dipole attraction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen (N), oxygen (O), or fluorine (F).

Front

Which molecules exhibit hydrogen bonding?

Back

Molecules like NH3 (ammonia) exhibit hydrogen bonding due to the presence of hydrogen bonded to nitrogen.

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 type of intermolecular force is present in CO2?

Back

London Dispersion Forces.

Front

How do intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points, while weaker forces lead to lower boiling points.

Front

Which substance is predicted to have the lowest boiling point based on intermolecular forces?

Back

N2 (nitrogen gas) is predicted to have the lowest boiling point due to weak London Dispersion Forces.

Front

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

Back

London Dispersion Forces.

Front

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

Back

Larger molecules have stronger London Dispersion Forces due to increased polarizability.

Front

What is a dipole-dipole interaction?

Back

An attractive force between the positive end of one polar molecule and the negative end of another polar molecule.

Front

What is the significance of electronegativity in intermolecular forces?

Back

Electronegativity differences between atoms in a molecule determine the polarity and strength of intermolecular forces.
