First of all we simply discuss that there are two major types of forces in chemical substances.  Intramolecular forces Intermolecular forces Note: Here we will discuss about the intermolecular forces only. Intermolecular forces: As the word "inter" is clearly depicting the meaning of term "intermolecular forces".  Those forces which exist among molecules. These are weak forces and controlling the physical properties of substances. There are following types of intermolecular forces. and intermolecular forces are also known as van der waal forces . Types: Ion-dipole forces Dipole-dipole forces Hydrogen Bonding London dispersion forces /Instentaneous dipole-induced dipole forces  1.Ion-dipole Forces. Ion-dipole Forces originate when an ion come across a polar substance. For example when sodium chloride ( ionic compound) is dissolved in water( polar molecule) , ion -dipole forces occurs between sodium ion to water  and chloride ions to water. Water encircles the sodiu...
