How do you know if the CH2OH will point equatorial up or axial down (up or down I guess) in the chair or haworth? They seem to always point up; when will I have a situation where it points down and how would I know in the name or elsewhere if the CH2OH should be pointing down?
Can you tell if the ring will be beta or alpha in the haworth projection, chair conformation by just looking at the Fischer projection, or must you be told first before creating the two from the Fischer? If so, could someone explain how? I've seen a bunch of websites and they all seem to say...
Oh wow , I forgot that it was H+ so it wouldn't violate any rules of having more than 8 electrons in N's octet. That makes sense, but how would we determine that the NH2 group gains the hydrogen in protonation rather than the oxygen on the methoxy group?

None
The Attempt at a Solution
H2F is more acidic as the answer. However, I was told in class that there were several factors affecting acidity, with some having more weight such as resonance>atomic radius>...
So I have this question that asks which is the strongest base. I have one structure with a benzene ring with an NH2 group on one side and a methoxy group on another side. Automatically I knew that the NH2 group would be what is protonated in the situation that this structure acts as a base and...
Does resonance affect the acidity of an acid (or the basicity of its conjugate base) if the resonance isn't delocalizing the charge on the atom that is directly attached to the atom with the proton, hydrogen itself.
For example a benzene ring with a carboxylic acid group attached to one side...
Yes - the two hydroxyl groups on the same side as the alkene in the ring are the ones that can be deprotonated creating several resonance structures for both situations. I was wondering what the reason for the hydrogens on the carbons and alkanes in general being so hard to deprotonate...
So in my organic chem class we learned how to choose the most acidic hydrogens on a molecule based on the stability of the conjugate base of that molecule. And then we used various factors to determine the stability of the conjugate base such as resonance (how resonance may help the negative...
So I learned that SN1 reactions require a polar protic solvent or it won't occur. For E2 I learned that polar aprotic solvents are favored, at least I think. I wasn't sure if it was stated that for an E2 reaction polar aprotic solvents were required or favored like for an SN2 reaction? Could...
Hi - really basic question here, but I was wondering. In biology it's said that catabolic reactions which break something down release energy, making such exergonic. In chemistry it is said that breaking bonds is endo-thermic. This seems counter-intuitive to me? But, I realize it's because the...
So I worked out the problem. Using the number of moles of O2 I found from using PV=nRT, I found that 0.818 moles of SO3 would be formed. Using stoich. to find the number of moles of SO2 and then using those number of moles, I found that 0.781 moles of SO3 would be formed. That means that SO2 is...
The SO3 is the product and what's left. I understand now. Seems like I forgot how to do limiting reactant problems and had to look back on some old problems. I did my stoichiometry wrong also because I didn't account the moles of SO3 into this...
Oh I forgot to balance it.
2SO2 (g) + 1O2 (g) = 2SO3 (g)
That's the equation, thanks didn't catch that.
So should I subtract the moles and then use PV=nRT or use the sum of the moles in PV=nRT. What's left is what I'm unsure of. Here I think since it's a limiting reactant and there's more moles...
