Exp 3 Bonding CUA Prep

Front

What is a lone pair?

Back

A pair of non-bonding electrons.

Front

How does a strong intermolecular force (IMF) affect boiling point?

Back

A strong IMF increases the boiling point.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve stealing/giving electrons, while covalent bonds involve sharing electrons.

Front

How can a molecule be classified based on polarity?

Back

A molecule can be classified as polar or nonpolar.

Front

What is a polar covalent bond?

Back

A covalent bond where electrons are shared unevenly or unequally.

Front

Define ionic bond.

Back

A bond formed by the transfer of electrons from one atom to another.

Front

Define covalent bond.

Back

A bond formed by the sharing of electrons between atoms.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond.

Front

What is a nonpolar covalent bond?

Back

A covalent bond where electrons are shared equally between atoms.

Front

What are intermolecular forces?

Back

Forces that occur between molecules, affecting physical properties like boiling and melting points.
