Why does Carbon not form an ionic bonds?
There are two main reasons for not forming an ionic bonds.
- It could gain four electrons forming C4– anion. But it would be difficult for the nucleus with six protons to hold on to ten electrons, that is, four extra electrons.
- It could lose four electrons forming C4+ cation. But it would require a large amount of energy to remove four electrons leaving behind a carbon cation with six protons in its nucleus holding on to just two
Why are covalent compounds poor conductors of electricity?
Covalent compounds are formed by the sharing of electrons. Since the electrons are shared between atoms and no charged particles are formed, such covalent compounds are generally poor conductors of electricity.
What is meant by catenation?
The unique ability to form bonds combining one atom with other atoms of carbon, giving rise to large molecules is called catenation.
What is Glacial acid?
