Question 28

Polarity

Answer 28

The greater the electronegativity different between atoms in a bond, the more polar the bond

Question 29

Contains bonds between atoms that do not a significant difference in electronegativity

Question 31

Intermolecular forces

Answer 31

These are forces between molecules | They determine melting points, freezing points, and other physical properties

Question 32

Non-polar solvents

Answer 32

Consists of non-polar molecules | Solvent - solute molecular interaction must be stronger than the solute
