like dissolves in like.ionic compounds dissolve in polar solvents becoz of dieletric constant ,hydration energy, and lattice energy .then explanation 4 non polar in non polar like benzene in ccl4

Dear Charitha,

There will be Induced Dipole Dipole Interactions also called "London Dispersion Forces"between the molecules of Non Polar Compounds . This is caused by Instantaneous Dipoles created in non polar molecule 
Suppose take some small Molecule ( Non polar ) or at least a He Atom ..at a particular instant The electrons of the atom for ex.are left side .. i mean the electrons revolve round the nucleus and suppose they are at left side of atom at some particularinstant. Then There will be Very small Negative Charge Developed on the left side and Very Small Positive charge on right side .. Now Consider this Atom goes near another atom ..The first atom we took ie, the charged atom(partially) induces the dipole creating Dipoles on its near by atoms or(molecules ) See the resource down for diagrammatic : ) 

This can be understood by ...ex you take H-Cl which is Polarized  ...+     ...-
                                                                                      H  ----Cl       
                                                                                        : ..-          :.. +   
                                                                                           C ======C  
when brought near ethene(almost Non Polar) is polarized like the above : ) 

Best Of luck
