When the initial and final states are degenerate, no structural evolution of the system will have occurred after transit of the energy ...

... Now we have a carbon-carbon bond present. You will notice that we are still obeying the fundamental octet rule. Each carbon is forming four σ-covalent bonds and thus has eight electrons in its valence shell. Question 5.2 Draw a Lewis dot-cross diagram for ethane. The next alkane contains three carbo ...
