Intermolecular Forces

Question 0

London forces

Answer 0

induced dipole forces
oppositely charges ends of the 2 dipoles attract each other
occurs between 2 non-polar atoms
melting point increases while the molar mass increases and surface area

Question 1

intermolecular force

Answer 1

a weak force of attraction between the molecules of a substance or between the atoms of a nobel gas
van der Waals force

Question 2

dipole-dipole

Answer 2

attractive forces between polar molecules

Question 3

hydrogen bond

Answer 3

special dipole-dipole
forms when:
1.) hydrogen atoms bond covalently to a small atom with a high - electronegativity
2.) polar molecules are formed which have relativly large S+ and S - - charges
