Document Summary
Identify stereocenters, identify the stereoisomers of a compound and determine their stereochemical relationships. Draw a mechanisms for all the types of reactions we have done in lab so far (sn1, sn2, bromination and oxidation) Determine what type of reaction will occur, given reagents, but no products. Do typical calculations related to stoichiometry in a reaction (figuring out limiting reagent, calculating % yield, etc. ) Determine the structure of a compound given its molecular formula, the ir, 1 h. You are expected to know the relative stretches of functional groups (o h, n h, c h, etc. ). You will be expected to know the relative chemical shifts for different protons and carbons. Substituted benzene and their characteristic absorption bands in the aromatic region. C-h out-of plane bending vibrations of substituted benzenes (cm -1 ) Monosubstituted benzene 770 - 730 710 - 690. Hybridization affects the bond lengths, and bond strength.
