In this lecture, I'd like to examine a few important reactive intermediates that can be produced from a methane molecule. Now, reactive intermediates are simply molecules or compounds that are too unstable and reactive to exist for a very long time. So they exist for a very short time, and they react with other compounds and molecules to produce new compounds. So let's look at the following methane molecule. So, in this react here, we have the following ch bond that dissociates. So this bond breaks in such a way that the two electrons go directly onto our H atom.
