Name the types of intermolecular bonding from weakest to strongest
1) van der waals, 2) permanent dipole-dipole, 3) hydrogen
1 of 5
Whats happens to form van der waal forces?
charge clouds moving, temporary dipole where opposites attract, created & destroyed but overall attraction
2 of 5
Why are some van der waal forces stronger in some molecules?
larger the molecule-more electrons, more surface area=increased van der waal forces, higher melting/boiling point
3 of 5
Between which elements do hydrogen bonds form and why?
H with O or F or N, very electronegative-bonds so polarised that H forms bonds with lone pair
4 of 5
What is a permanent dipole-dipole force?
delta + and - on polar molecules= weak electrostatic attraction
