Fumaric Acid to Maleic Acid (Hydration or Reduciton?)
« on: March 17, 2014, 10:55:03 PM »
Hi Folks,

My first post here.. please excuse my limited chemistry knowledge.

My understanding of oxidation and reduction in organic chemistry is as follows:

- Gain of electron
- Gain of Hydrogen
- Loss of Oxygen
- Loss of = or triple bond

- Loss of electron
- Loss of Hydrogen
- Gain of Oxygen
- Gain of = or triple bond.

Now... is this correct?

If so, then why do we consider the formation of Maleic Acid from Fumaric Acid (in the Kreb's cycle) as a Hydration and not a Reduction reaction? considering that we indeed gain H and lose a double bond?

We also gain an Oxygen (in the -OH) bond formed... doesn't that make it oxidation?

I'm confused.

What's the best way to explain Oxidation and Reduction reactions in Organic Chemistry?

Thanks in advance guys!

Think of reduction as a reduction in the number of carbon bonds to electronegative elements. :).  Best way I ever learned it, and as it applies to orgo, the most useful definition IMHO.
