Which of the following is/are correct about ionic bonding?
Ionic compounds are soluble in polar solvents and insoluble in non-polar solvents.
Non polar solutions consist of molecules that are equally charged on all sides of the molecule. So these molecules keep to themselves and don't interact with other charged molecules, seeing as they're already neutral and stable.
Polar solutions, on the other hand, consist of molecules that have a difference in charge across the molecule. so the bottom of the molecule might be more negatively charged than the top of the molecule, due to differences in electro-negativity of the molecule's atoms. So, if you put some ionic compounds (compounds that are charged) in with these polar molecules, they would readily mix, because they both hold charges and can therefore attract each other .
Ionic compounds generally have high melting and boiling points due to the strong bond between a positively charged ion and a negatively charged ions.
