Document Summary
30pts for free response: optical activity, speci c rotation, deciding whether something is enantiomer, identical, isomer, constitutional, conformational, chirality, and recognizing when something is chiral or not, enantiomer and diasteromer de nitions, recognizing chirality centers. Is something chiral: nomenclature with a stereo center. Identify r and s: matching two molecules with terms (diasteromer, etc. , nmr, chemical shift, number of signals, splitting, more splitting, more comprehensive, spectrum and solving the structure, substitution. Nd all stereocenters in a big molecule. Molecule drawn out, and predict the nmr graph: mass spectometry question. Given ir and nmr data, and predict the fragments. And guring out the nal structure: more general spectroscopy question. Ir, nmr, mass spec. , compare: 7 pt sn1 or sn2 complete mechanism. Provide a detailed stepwise mechanism for the reaction below. Include all the intermediates, the transition state, draw all arrows to show electron movement.
