Halides of Be dissolve in organic solvents while those of Ba do not. Why is it so ? |
|
Answer» ides of beryllium have high ionization enthalpy and so their halides are covalent in NATURE. WHEREAS the halides of barium have low ionization enthalpy and so their halides are ionic in nature. We know that covalent COMPOUNDS are soluble in organic SOLVENTS which is not EXHIBITED by ionic compounds. Hence, the halides of beryllium which are covalent in nature soluble in organic solvents whereas the halides of barium which are ionic in nature and do not dissolve. |
