Ah, you're also retaking unit 1? Me too. Except I'm doing mine on Wedensday.
Even though it's surprisingly easy now, I always find it's possible to make silly mistakes.

Good luck!


But it's this Thursday? How can you do it on a different day?? :s-smilie:

I was under the impression the 23rd was on Wednesday!

Whoops. Obviously it wouldn't be right for me to take the exam on a different date...:colondollar:

Zwitterion is a dipolar ionic form of an amino acid by the donation of a hydrogen ion from a carboxyl group to an amino group , both charges are present and hence cancel out

Describe proton NMR (6)


spectroscopic analysis technique, chemical shift values show the type of proton environment, number of peaks equals number of types of proton environments, splitting patterns show the number of protons attached adjacent carbon atoms. relative peak area is proportional to number of protons in that environment. D2O addition OH/NH peaks removed
