INTERMOLECULAR FORCES

Front

What explains the very high melting and boiling point of water?

Back

Strong hydrogen bonds between water molecules.

Front

Does NH3 have hydrogen bonding?

Back

Yes.

Front

Determine the type of intermolecular force present in SiO2.

Back

Covalent network.

Front

What is the basis of a metallic bond?

Back

The attraction between positive metal ions and free floating electrons.

Front

What are intermolecular forces?

Back

Forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).

Front

Name the three main types of intermolecular forces.

Back

Dipole-dipole interactions, hydrogen bonding, and dispersion forces.

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

What are dispersion forces?

Back

Weak intermolecular forces that arise from temporary dipoles in molecules.

Front

How do dipole-dipole interactions occur?

Back

They occur between polar molecules where the positive end of one molecule is attracted to the negative end of another.

Front

What is the significance of molecular shape in determining intermolecular forces?

Back

The shape affects polarity and the strength of intermolecular forces, influencing properties like boiling and melting points.
