Brushing up on Organic Chem

[Broke 0]

I was reading some Wikipedia pages on Organic chemistry specifically about aldehydes.

Now it said that HCHO can be Methanal, but to me that would make one think that there is an OH bond in there as opposed to saying that H2CO is Methanal.

Now that I think about it the CO group could also be misread as a Carboxy group.

What do you guys think

dude its friday and its almost beer time... while I understood what you just wrote, that much thinking seriously makes my brain hurt at this hour... thats like a Monday morning question....

Then you would be telling me it is too early in the week to think

H- C- OH would not be a stable molecule.

Carbon likes 4 bonds.... like methanol (CH3OH)

Methanal (aka Formaldehyde, CH2O) is formed by oxidising methanol - but there is a double bond with the O and two single bonds with the H, satisfying the 4 bonds to carbon.

Now I am looking at something saying that Glucose is an Aldehyde, but none of the models of the ring form of the molecule show where the double bonded oxygen is.

Yes I do know that HCHO is an unstable molecule. A model written like that is missing 2 Hydrogen Molecules.

ok... I couldn't avoid the traumatic memories of Organic Chem, so I might as well dance with the monsters.

Glucose is an aldehyde with a link to what I'm guessing is wiki page you were talking about (looking at this diagram, the double bond to the oxygen is at the top)

H O

. C

H C OH

H C OH

HO C H

H C OH

. CH2OH

What's confusing you might be how they have depicted the molecule. There are open-chain (acyclic) and ring (cyclic) forms, the latter being the result of a covalent bond between the aldehyde C atom and the C-5 hydroxyl group to form a six-membered cyclic hemiacetal. Then we would also discuss whether it's in chair or boat and stereoisomers.... but if you want to discuss gluconeogenesis, I will have to start barking at the moon.

I am just studying up because I want to get back into school next semester. I did a semester of Organic and don't remember crap.

Also with my job I play with a lot of formaldehyde

Look here for some easy reading on brushing up. (Not saying you're a dummy, but it's much nicer to breeze through than a thick and heavy text

I think I'll just open my Embryology text and read the chapter about Hermaphrodytes again

SEE NOW..... Embryology was COOL! Like WAY COOL! ULTRAMAX GREEN COOL! All the layers and the folding and .....

You can not say that THIS is not amazing!

Actually Embryology helped me with my Anatomy of the cardiovascular and Neurological systems for my EMT
