Answer
| Electrovalent Compound (MgCl2) | Covalent Compound (CCl4) |
|---|---|
| MgCl2 is formed by transfer of electrons from Magnesium to Chlorine so it consists of ionic bonds. | CCl4 is formed by sharing of electrons between Carbon and Chlorine so it is made up of covalent bonds. |
| MgCl2 consists of ions Mg2+ & Cl-. | CCl4 consists of molecules — 1 Carbon and 4 Chlorine atoms form a molecule of CCl4. |
| MgCl2 has higher melting and boiling point. | CCl4 has lower melting and boiling point. |
| An aqueous solution of MgCl2 functions as an electrolyte and conducts electricity. | CCl4 does not conduct electricity in solid, liquid or molten state. |
| MgCl2 is easily soluble in water but insoluble in organic solvents. | CCl4 is insoluble in water but soluble in organic solvents. |
