intermolecular forces 1

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

What is hydrogen bonding?

Back

Hydrogen bonding is 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 molecule has strong hydrogen bonding?

Back

NH₃ (ammonia) has strong hydrogen bonding due to the presence of nitrogen.

Front

What type of intermolecular forces are present in H₂?

Back

H₂ exhibits London dispersion forces, which are weak intermolecular forces.

Front

How do strong intermolecular forces affect boiling points?

Back

Strong intermolecular forces lead to high boiling points because more energy is required to overcome these forces.

Front

Which molecule has the highest boiling point: H₂, F₂, Cl₂, or O₂?

Back

Cl₂ (chlorine) has the highest boiling point among these molecules.

Front

What is the role of London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, present in all substances.

Front

What is a dipole-dipole interaction?

Back

Dipole-dipole interactions are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

Front

What is the significance of electronegativity in hydrogen bonding?

Back

Electronegativity determines how strongly an atom attracts electrons; in hydrogen bonding, highly electronegative atoms (N, O, F) create strong attractions with hydrogen.

Front

Which molecules can form hydrogen bonds with water?

Back

Molecules like NH₃ (ammonia) can form hydrogen bonds with water due to the presence of N.
