Front

What happens to the boiling point of a substance when its intermolecular forces are weaker?

Back

The boiling point is lower.

Front

Does methane (CH4) exhibit hydrogen bonding?

Back

No, CH4 does not have hydrogen bonding.

Front

Which of the following substances will take the longest to evaporate: CH3CH2OH, CH3OH, or CH3CH3?

Back

CH3CH2OH will take the longest to evaporate.

Front

If fluorine is stronger than carbon in a bond, what charge will fluorine have?

Back

Fluorine will have a slight negative charge.

Front

What type of intermolecular force is present in a sample of water?

Back

Hydrogen bonding.

Front

Define intermolecular forces.

Back

Intermolecular forces are forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions).

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole attraction that occurs between molecules when hydrogen is bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine.

Front

What is the relationship between intermolecular forces and evaporation rate?

Back

Stronger intermolecular forces result in a lower evaporation rate.

Front

What is the significance of electronegativity in bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond, influencing bond polarity and the type of intermolecular forces.

Front

What is the difference between covalent bonding and ionic bonding?

Back

Covalent bonding involves the sharing of electron pairs between atoms, while ionic bonding involves the transfer of electrons from one atom to another, resulting in charged ions.
