Intermolecular Forces
Different types
-
Dipole-dipole forces
Polar molecules have dipoles which are charged due to different electronegativity values this dipoles will feel electrostatic attractions to other polar molecules.
Hydrogen bonding
Occur in molecules where a Fluorine a Nitrogen or an Oxygen atom are bonded to a hydrogen. The big difference in electronegativity creates a positive dipole in the hydrogen which will than be attracted to another Fluorine, Nitrogen or Oxygen
Deduction
-
-
If there is a polar molecule and an O, N or F is bonded with oxygen than there will be London, dipole-dipole and Hydrogen bonding
Physical properties
Taking into consideration the order strength presented in the top branch of this mind map we can conclude that compounds which have hydrogen bonding will have a bigger melting and boiling point when comparing to those with just London forces as it is required more energy to break the hydrogen bonds. The opposite happens to volatility and solubility where stronger forces will hold the molecules stronger together thus not letting it break as easily making it less soluble
As for electrical conductivity components with weaker intermolecular forces will be more conductive as the electrons move more freely creating a current
