Hi fellow chemists. Im currently batteling to dry a morpholine sample. I have followed the literature and added NaOH to no avail. I have the water layer seperating from the organic phase once I add the NaOH however apon distilling the organic layer it still contains water. I have tried NaOH as well as MgSO4, nothing is removing the water. How can I get this sample dried and completely anhydrous?
I’m pretty sure the last two are aromatic and that the first two are not. Why is the third one aromatic? Is the electrons highlighted in red in the continuous pi system?
How is this not racemic? Is this not an enantiomer with each having different R, S configurations?
I am SOOOO confused about deciding what becomes a dash or a wedge. I don’t even think I am doing this right at all lol. Can someone help me out plssss and give out some rules you guys use to draw out the iupac name with the r/s
Hi everyone, I'm having a lot of trouble with this conceptually. I thought it would be Most acidic: I > III > II Least acidic, but I'm not sure why that's wrong, since II is adjacent to some pi bonds doesn't that stabilize the structure? And I is the most acidic because its conjugate base is stabilized by resonance with the carbonyl, while III is also somewhat stabilized by resonance, so I'm confused about why II would be considered more acidic than III.
This is from my second year uni organic chemistry practice questions, any explanation is appreciated
I was always taught through university that the one with the highest peak is always the RDS. But to do this question, I must draw a peak larger than the RDS. This is a potential energy diagram, am I tweaking?
edit: is it because it’s irreversible, then it’s possible?
I know I'm probably describing it poorly, but WHY wouldn't I just add more dots in some situations? For example, here I genuinely don't know why I wouldn't add 3 bonds and have 1 pair of dots on each side.
Good day! I'm gonna do a method validation and I've been told by my professor to use AOAC as my source. I'm having trouble finding a free source (college undergrad) of the methods and I'm wondering if there is any of it out there, even old ones. Do I really need to pay for it or request access from AOAC itself?
Hello. Tomorrow I have organic nomenclature and I just began thinking about how to name systematically certain compounds like cyclohexane-1,2,3,4,5,6-hexol or even 1,4-dimethylcyclohexane, since i don't know how the priorities work. I stumbled upon r/s descriptors, yet i don't know how ro use them in these cases. For example, what is cis-1,4-dimethylcyclohexane using that system? What about the trans diastereoisomer? And what abour all the stereoisomers of cyclohexane-1,2,3,4,5,6-hexol? Which is carbon 1 for that matter?
Edit: I forgot to mention that for some reason my ip address is banned on stackexchange for some reason, since I have never used it other than for checking stuff
Hi everyone! I’m a first-year Chemistry BSc student and I’d love to hear from some second/third-year students (or graduates) about things you wish you’d known when you started university. What do you wish you had done differently in first year, or what habits/resources/study methods ended up helping you the most?
(High school chem education) I recently tried to come up with the structure for nitrate, and my whole process is basically documented on the left. I have learned that the correct structure is the one on the left. However, I don't understand why the right structure is correct instead of the left one.
They both have 24 total electrons (5+6+6+6+1, for N, O3, and -) and both have a total charge of -1. Plus, the correct version would seemingly require the double-bonded O atom to randomly give one of its electrons to another to accommodate the coordinate bond, which doesn't seem like it should be possible. Can anyone make this make sense?
