Intermolecular Forces

Front

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

Back

Strong hydrogen bonds between water molecules.

Front

Does HCl have hydrogen bonding?

Back

No.

Front

What are the intermolecular forces present in NH3?

Back

Hydrogen bonding.

Front

What type of intermolecular force is present in HCl?

Back

Dipole-dipole.

Front

The weaker the intermolecular forces of a substance, the _____________ the boiling point.

Back

lower.

Front

Define intermolecular forces.

Back

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

Front

What are hydrogen bonds?

Back

Strong dipole-dipole attractions that occur between molecules containing hydrogen bonded to highly electronegative atoms like N, O, or F.

Front

What is the primary intermolecular force in nonpolar molecules?

Back

Dispersion forces.

Front

How do dipole-dipole forces arise?

Back

From the attraction between the positive end of one polar molecule and the negative end of another.

Front

What is the relationship between intermolecular forces and boiling point?

Back

Stronger intermolecular forces result in higher boiling points.
