Intermolecular Forces Review

Front

What explains the very high melting and boiling point of water?

Back

Strong hydrogen bonds between water molecules.

Front

Do polar and nonpolar molecules mix together homogenously?

Back

False.

Front

What forces will a molecule with only London dispersion forces have?

Back

LD only.

Front

How do you determine if a molecule is polar or nonpolar?

Back

By analyzing its shape and the electronegativity of its atoms.

Front

Which of these is the strongest intermolecular force?

Back

Ionic bonding.

Front

What are dipole-dipole forces?

Back

Attractive forces between the positive end of one polar molecule and the negative end of another.

Front

What are London dispersion forces?

Back

Weak intermolecular forces arising from temporary dipoles in molecules.

Front

What is hydrogen bonding?

Back

A strong type of dipole-dipole interaction that occurs between molecules containing hydrogen bonded to highly electronegative atoms like N, O, or F.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a net dipole moment due to their shape and electronegativity differences, while nonpolar molecules do not.

Front

What is the significance of molecular shape in determining polarity?

Back

The shape of a molecule affects the distribution of charge, which determines if it is polar or nonpolar.
