Why is that, even after being covalent, carbon(C), with a valency of 4, isn’t able to form di-atomic molecules, when atoms of hydrogen(H) and nitrogen(N) can?
In: Chemistry
Because electrons are all negatively charged and therefore repulse each other. A quadruple bond would be unstable. In Nitrogen, you have a triple bond to the other nitrogen atom, but also a freue electron pair opposing the bond, which pushes the other electrons to one side, making it easier to bond. In Hydrogen there is no second electron, therefore no repulsion (and no possibility for a second bond whatsoever)
