Beryllium halides are covalent whereas magnesium halides are ionic. Why? |
| Answer» SOLUTION :D ue to small size of `Be^(2+)`, the charge density is very high. According to Fajan's RULE, cation with small size has high polarising power and prefers to form COVALENT bonds. So BERYLLIUM HALIDES are Covalent in nature. | |
