Why covalent compiunds have low melting point than ionic compounds |
| Answer» Covalent compounds have bonds\xa0where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include\xa0lower melting points\xa0and electrical conductivity compared to\xa0ionic compounds.\xa0The\xa0melting point\xa0is\xa0low\xa0due to weak van der Waal\'s forces of attractions between the\xa0covalent\xa0molecules. The force of attraction between the molecules of a\xa0covalent compound\xa0is very weak.<br>Covalent compounds have bonds\xa0where electrons are shared between atoms.
