What's more acidic? An ether, or an aldehyde?
e.g. CH3-O-CH3 vs. CH3CHO
Thanks!

The aldehyde is more acidic. And the acidic proton is NOT the aldehyde one (i.e., the one attached directly to the carbonyl). It's the methyl group protons that are acidic.What's more acidic? An ether, or an aldehyde?

Yes. A carbonyl is electron withdrawing, while an alkoxy group is donating. So you could explain their relative acidities in terms of whether they stablize or destabilize the conjugate base's negative charge.Q,
Just a curious question, but the acidity of an ether and aldehyde and other organic groups can also be explained in terms of their electron withdrawing and electron donating capacities right???
Yes, except that alcohols are usually more acidic than aldehydes, and the acidities of carbonyl compounds overlap with one another. Also, don't forget about alkynes; they're fairly acidic as far as hydrocarbons go. So I would make your list like this:Ethers are not very acidic at all. Remember that acids are supposed to be good at donating protons.
I've always wondered, is there a general acidity spectrum of organic compounds?
(Most acidic) Carboxlylic acids > Aldehydes > Alcohols > Esters > Ketones > Ethers > Alkanes (Least acidic)
Something like this??

You did NOT just post in this thread to make faces. I expect more from you.
