Intermolecular Forces

Front

What type of molecule is likely to dissolve in oil?

Back

Nonpolar molecules, such as CCl4, are likely to dissolve in oil.

Front

Rank the following intermolecular forces from strongest to weakest: covalent bond, London forces, hydrogen bond, dipole-dipole attraction.

Back

Covalent bond > Hydrogen bond > Dipole-dipole > London forces.

Front

Which substance is expected to have the weakest intermolecular forces?

Back

Substance C, with a boiling point of 25 °C, has the weakest intermolecular forces.

Front

What determines the polarity of a bond?

Back

The polarity of a bond is determined by the difference in the electronegativities of the two atoms.

Front

What type of intermolecular force is present in HCl?

Back

Dipole-dipole attraction.

Front

Define intermolecular forces.

Back

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

Front

What is the relationship between boiling point and intermolecular forces?

Back

Generally, substances with stronger intermolecular forces have higher boiling points.

Front

What are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces arising from temporary dipoles in molecules.

Front

How do hydrogen bonds differ from dipole-dipole interactions?

Back

Hydrogen bonds are a specific type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

What is the significance of electronegativity in determining molecular polarity?

Back

Electronegativity differences between atoms in a molecule determine the distribution of electron density, affecting the molecule's polarity.
