Question 1

Intermolecular forces

Answer 1

Weak attractive forces between molecules which determine physical properties

Question 2

Electronegativity

Answer 2

Key factor which determines the electron distribution in molecules

Question 3

Bond polarity

Answer 3

Covalent bonds can be polar or non-polar. If they have a difference in electronegativity of atleast 0.5-1.6 it will be polar
In non-polar the electron cloud is positioned symmetrical
In polar bonds the electron cloud is skewed towards the nucleus of the more electronegative atom.
