Front

What determines if a molecule is polar or nonpolar?

Back

The distribution of electron density and molecular geometry.

Front

Define electronegativity.

Back

Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a nonpolar covalent bond?

Back

A bond where electrons are shared equally between two atoms.

Front

What is a polar covalent bond?

Back

A bond where electrons are shared unequally between two atoms.

Front

What is the significance of the molecular geometry in determining polarity?

Back

Molecular geometry affects the distribution of charge, influencing whether a molecule is polar or nonpolar.
