Ppt about collision

1. • is a special type of dipole-dipole
interaction that occurs in molecules
having a hydrogen atom bonded to an
electronegative atom such as fluorine,
oxygen, or nitrogen
• contains O-H, N-H, and F-H bonds
• it is the strongest intermolecular
force of attraction among the three
Hydrogen
bond

4. from Weakest to strongest
forces:
 dispersion forces (or London dispersion
forces)
 dipole–dipole forces
 hydrogen bonding (a special dipole–dipole
force)
Types of Intermolecular
Force

5.  the IMFA in solids are very strong, thus the
particles are compact
 the IMFA in liquids are not strong enough to keep
the particles remain in fixed position so liquids
generally tend to resemble the shape of their
containers
 the IMFA in gases are extremely weak or almost
eligible thus, particles are free to move around
Intermolecular forces are involved in
phase changes:
