Question

why can't the 6 carbons get bonded with all double bonds without any hydrogens bonded in a closed ring structure?

Answer 1

Answer:

The atomic number of Carbon is 6 with an electronic configuration of 2, 4. Hence, carbon has 4 electrons in its valence shell. Carbon can lose or gain 4 electrons in order to gain stability. It cannot gain four electrons as carbon atom having 6 protons is very small to handle 10 electrons and it cannot donate electrons as it needs a lot of energy to do so. Hence, it cannot form C

4+

cation or C

4−

anion and thus forms a covalent bond.
