Torsional strain

Would torsional strain be negative if you were moving from a less stable conformation to a more stable one?

Re: Preference in numbering

Do halides have priority over double bonds? I'm referring specifically to 1,6-dichloro-cyclohexane on page 105 of the course reader.

Placement of halide substituent in IUPAC name

Do halides always come first in the name or does it go alphabetically? (I.e. If there was an ethyl and a fluorine anion attached to the same carbon, which would be listed first?)

Preference in numbering

I know you give preference to double bonds and functional groups when numbering, but which is more important? If you had a choice between setting a functional group at the second carbon or a double bond starting at the second carbon, which would you choose?

Possible error on page 163 of ochem textbook

On page 163 of the Intro to Organic Chemistry textbook, it says "When \Delta G^o r <0, the exergonic reaction is favorable and K>1. When \Delta G^o r >0, the endergonic reaction is unfavorable and K<1." I believe there's an error here, but I just wanted to make sure. Im also unsure about w...

Is it possible to have two nucleotides in a rxn?

In example 2 on course reader page 85, it is stated that a nucleophile (denoted :Nu) donates electrons to and bonds with the central carbon atom. The Cl connected to the carbon is also electron rich because of its higher electronegativity. Is it considered a nucleoniphile as well or do nucleophiles ...

Converting 2nd order diff rate law to integrated rate law

I'm confused as to where the goes when you integrate the 2nd order differential rate law, , to get . Are we assuming a equals 1? If so, why?

Max potential

It is stated that potential is maximized when the process is reversible and there's very little current, but what is the explanation behind this?

Definition of cell and redox potential

What is the difference between E0redox and E0cell? On page 50 of the course reader, when we are given two half reactions, we want to reverse the sign of the iron half reaction to get a positive cell potential. In the gold example on page 52, E0redox is allowed to be negative. Why is this?
