Bonding & Intermolecular Forces Review

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and nonmetals.

Front

List three characteristics of ionic compounds.

Back

1. High melting and boiling points. 2. Usually solid at room temperature. 3. Conduct electricity when dissolved in water.

Front

What type of bond is formed when an alkali metal combines with a halogen?

Back

Ionic bond.

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

Which type of intermolecular force is present in H2S?

Back

Dipole-dipole forces.

Front

What is the boiling point trend for ionic compounds compared to covalent compounds?

Back

Ionic compounds generally have higher boiling points than covalent compounds due to stronger ionic bonds.

Front

What is a characteristic of covalent compounds?

Back

Covalent compounds typically have lower melting and boiling points compared to ionic compounds and may exist as gases, liquids, or solids at room temperature.

Front

What is the London Dispersion Force?

Back

London Dispersion Forces are weak intermolecular forces arising from temporary dipoles in molecules, present in all molecules but are the only forces in nonpolar molecules.

Front

What type of bond is present in Cl2?

Back

Covalent bond.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond, influencing whether the bond is ionic or covalent.
