Intermolecular Forces

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.

Front

What type of intermolecular force is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

Does CH4 have hydrogen bonding?

Back

No, CH4 (methane) does not have hydrogen bonding because it does not contain highly electronegative atoms bonded to hydrogen.

Front

Which substance has the weakest intermolecular forces: CH4, NaCl, H2O, or MgF2?

Back

CH4 has the weakest intermolecular forces among these substances.

Front

What is molecular polarity?

Back

Molecular polarity refers to the distribution of electrical charge over the atoms in a molecule, which affects the strength and type of intermolecular forces present.

Front

What type of intermolecular force is responsible for the attraction between polar molecules?

Back

Dipole-Dipole Interaction is responsible for the attraction between polar molecules.

Front

Why does water have a high boiling point compared to other molecular compounds?

Back

Water has a high boiling point due to hydrogen bonding, which requires more energy to break compared to other intermolecular forces.

Front

What is the role of electronegativity in determining intermolecular forces?

Back

Electronegativity differences between atoms in a molecule can create dipoles, leading to dipole-dipole interactions or hydrogen bonding.

Front

What is the difference between ionic bonds and intermolecular forces?

Back

Ionic bonds are strong attractions between charged ions, while intermolecular forces are weaker attractions between neutral molecules.

Front

What are London dispersion forces?

Back

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