Practice Final 2015 9b Alcohol vs Hydroxyl

If we were to be given the molecule instead of the IUPAC name, how would we differentiate between using the hydroxyl components of naming vs the alcohol components. (-ol vs hydroxy).

Re: Naming Help

Do the numbers need to be lowest according to alphabetical order or is the alphabetical order only relevant when arranging the name of the molecule?

Nucleophiles and Electronegativity

Taking into consideration question 4.4 in Intro to O Chem (Which is a stronger nucleophile and why? Br- or F-?). Answer: Br-.

Is the strength of nucleophiles dependent on electronegativity?

Re: Sproul Hall Chem14A Study Group

I know that midterm just passed, but would anyone be interested in getting study room in the first floor tomorrow night at around 7 to go over material from the last few lectures? Mostly over chapter 17 material covered this past Friday.

Re: Sproul Hall Study Group

Hey! Well for the next two nights I may be quite busy but I would be more than happy to have a study session on Thursday Night. I wont be back on the Hill until around 6 so do you think you could reserve a study room for the group? I think a solid time would be around 7 and up. What do you think?

H.W. Problem 1.55

Infrared spectroscopy is an important tool for studying vibrations of molecules. Just as an atom can absorb a photon of suitable energy to move an electron from one electronic state to another, a molecule can absorb a photon of electromagnetic radiation in the infrared region to move from one vibrat...
