Intermolecular Forces 1

Front

What are intermolecular forces?

Back

Intermolecular forces are 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 are the main types of intermolecular forces?

Back

The main types of intermolecular forces are London Dispersion Forces, Dipole-Dipole Forces, and Hydrogen Bonds.

Front

What are London Dispersion Forces?

Back

London Dispersion Forces are weak intermolecular forces that arise from temporary dipoles created when electrons move around a molecule.

Front

What factors can strengthen London Dispersion Forces?

Back

London Dispersion Forces can be strengthened by larger molecules with more electrons, as they have a greater polarizability.

Front

What are Dipole-Dipole Forces?

Back

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

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a partial positive charge on one end and a partial negative charge on the other.

Front

What is the significance of hydrogen bonds?

Back

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

Front

What holds ionic solids together?

Back

Ionic solids are held together by ionic bonds, which are the electrostatic forces of attraction between positively and negatively charged ions.

Front

How do ionic bonds differ from covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, resulting in charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the role of electronegativity in determining bond type?

Back

Electronegativity is the ability of an atom to attract electrons. A large difference in electronegativity between two atoms typically leads to ionic bonding, while a smaller difference leads to covalent bonding.
