What is polar solution and non-polar solution?

• Polar solvents have large dipole moments ( simply can be called charge difference); they contain bonds between atoms with very different electronegativities, such as oxygen and hydrogen.

• Non polar solvents contain bonds between atoms with similar electronegativities, such as carbon and hydrogen (think hydrocarbons, such as gasoline). Bonds between atoms with similar electronegativities will lack charge difference; it’s this absence of charge which makes these molecules “non-polar”.
