I have two Chemistry related questions that were in my AP Chem summer packet. The first has to do with Stoichiometry. It says, "Calculate the number of moles, molecules, and atoms in 60.0 g of boron triflouride. I calculated that there are .885 moles, and 5.33 x 10^23 ...

Organic chemistry: dehydrohalogenation
DrBob has essentially covered it. It is not that easy to generalise, you need to consider each halide looking for steric influences, stabilisation of a carbocation and stability of the product. Some general points: E1 is a two-step process of elimination ionization and ...

The topics of the questions you are asking are not covered adequately even in a college General Chemistry textbook. An Organic Chemistry textbook would be more helpful for most of the 13 questions. A good starting point for organic chemistry is the online textbook, General ...

Alkene formation is a 1,2-elimination reaction. Ether formation is a nucleophilic substitution with the protonated alcohol as substrate and a second molecule of alcohol as nucleophile.

I believe the nucleophile is the alcohol (more specifically, the O of the alcohol). See here. http://www.organic-chemistry.org/namedreactions/nucleophilic-substitution-sn1-sn2.shtm

you can also order the UPCO's Physical Setting CHEMISTRY... it has many helpful equations and it will make it easier to study and understand evrything... plus the book is cheap too.
