Intermolecular Science

Front

What is an intermolecular force?

Back

An intermolecular force is a force of attraction or repulsion that acts between neighboring particles (atoms, molecules, or ions).

Front

What are the main types of intermolecular forces?

Back

The main types of intermolecular forces are hydrogen bonds, dipole-dipole interactions, dispersion forces (London forces), and ion-dipole interactions.

What type of intermolecular force is responsible for the bonding in AlCl3?

Back

Dispersion force.

What intermolecular force allows table salt (NaCl) to dissolve in water?

Back

Ion-dipole.

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds are responsible for the high melting and boiling points of water.

Front

Which molecule has the lowest boiling point: BF3, H2O, or NaCl?

Back

BF3 has the lowest boiling point.

Front

What is an ion?

Back

An ion is a charged particle that can be either positively charged (cation) or negatively charged (anion).

Front

How do dispersion forces arise?

Back

Dispersion forces arise from temporary fluctuations in electron distribution within molecules, leading to temporary dipoles.

Front

What is the role of dipole-dipole interactions in molecular bonding?

Back

Dipole-dipole interactions occur between polar molecules and are responsible for the attraction between the positive end of one polar molecule and the negative end of another.

Front

What factors influence the strength of hydrogen bonds?

Back

The strength of hydrogen bonds is influenced by the electronegativity of the atoms involved and the distance between them.
