42
Q

Van der Waal’s forces

A
  • weakest intermolecular force
  • present in all compounds
43
Q

dipole-dipole forces

A
  • stronger than vdw
  • only exist in polar compounds
  • involves the alignment of partial + and partial - poles
44
Q

hydrogen bonding

A
  • strongest intermolecular force
    2 requirements:
    a. there must be H atom covalently bonded to an electronegative atom (O,N,F)
    b. the other molecule must have a lone pair in its electronegative atom (O,N,F)
