Methane to methanol, electrons?
« on: October 12, 2013, 12:32:03 PM »
What exactly is happening with the electrons when methane is converted to methanol?

I know this is an oxidation reaction and there is a loss of electrons, but how are they distributed? Anyone know of a good visualization of this?

though from the viewpoint of the carbon this might be considered to be an oxidation reaction, for the molecule as a whole it isn't: it's just an insertion of atomar oxygen into one of the C-H bonds

so, for the molecule as a whole there is no electron loss whatsoever

Thanks!

So how does this release energy then and produce a higher oxidation level for the carbon?

there are many pathways to release energy, but more often than not it's in the form of heat

to put it simple: everytime you connect two atoms of different electronegativity, the electron distribution inbetween them will become asymmetric.
in a H - C bond, carbon is more electronegative than hydrogen, and if you wish, you might say that hence carbon will have "oxidized" the hydrogen (itself becoming reduced thereby as a consequence) : H  :rarrow: H+ , C  :rarrow: C-
replacing H by O , you exchange an element that is less electronegative than carbon with an element that is more electronegative than carbon. hence the respective distribution could be described like this:
:rarrow: C+ , O  :rarrow: O-

hence , in the net process, by replacing hydrogen with oxygen, carbon has changed from C- to C+ along the way

that's what we call an "oxidation"

Thanks magician4.
