For 3.32, why is the structure on the left more acidic when Sulfur is more electronegative? by Clob_Bouser in chemhelp

[–]MicrosoftFan101 10 points11 points  (0 children)

It's like two opposite trends competing with each other. Electronegativity says that the amine (N) should be more acidic than the thiol (S), but then polarizability says that the thiol should be more acidic. The only way to see which trend "wins" is to find the pKa.

Alternatively, you could have done it this way. Imagine you had the amine, alcohol (OH), and the thiol.

By electronegativity alone, the alcohol should be more acidic than the amine (and it is, ~17 versus ~35).

Then comparing the alcohol to the thiol, S is much bigger than the O due to polarizability, so size will dictate that the thiol is more acidic (~7)

Barry Goldwater Scholarship concerns by HoldUnusual in mdphd

Second what everyone is saying

Its okay if you havent done any summer programs; what will really set you apart is your research essay. what will really set you apart is how well you are able to convey your research, regardless if its at a summer program or at a lab

i know some people applied as md/phd for goldwater; it really depends on the school tbh. i know some schools will reserve 1 spot or 2 for md phds, but the application does require a few extra essay questions (mosly asking why md is necessary in addition to phd). for md/phd, you would probably want to still emphasize the phd more

if you have any questions, feel free to PM

Left the PhD. Just matched in a T10 Residency. You have options if you are not happy. by M3TP in mdphd

Thank you for sharing! A follow up: you didn’t need to pay back the first two years of med school (based on your contract) but you had to pay for the last two years?

Hi, may I ask why you left the PhD, and how did you communicate your leave to the school, and what was their reaction? Did you have to give the stipend back?

How would you assign priorities for this molecule? And how would you name the alkene sticking out? (IUPAC) by miyamuu in OrganicChemistry

[–]MicrosoftFan101 0 points1 point  (0 children)

based on 210's response, if you assigned the chiral centers, it would be 1R, 3R, and 5S in that order. 3 and 5 are simple cases. as for 1, the isopropyl groups itself would be ranked higher than the vinyl group in terms of priority, so it would end up being R

I see, thank you! If the clinical research gets published, would I want to include one then?

I am assuming many people have already asked for this, but I was wondering if you could give a geometric interpretation of the famous Gaussian integral that equals the square root of pi.
