Study Guide Exam III Chapter 13:  NMR basic theory  Effect of a magnetic field on nuclei, focus on 13C and 1H.  Effect of field strength on energy states  Chemical shifts, shielding, and deshielding  Be able to recognize the difference between 13C and 1H spectra.  Be able to identify equivalent carbons and protons  Given a chemical structure, be able to predict how many signals there should be in the 13C and 1H spectra.  Be able to apply the n + 1 rule to decide upon the multiplicity of carbons and protons in 13C and 1H spectra.  Index of hydrogen deficiency  Know where the infrared absorptions occur for alcohols, amines, and carbonyl- containing compounds.  Understand how to deduce that an oxygen-containing compound might be an ether, acetal, or ketal. (absence of carbonyl and alcohol absorptions).  Given nmr and spectral data deduce the structure of a chemical compound.  TMS and why it is used as a standard in 13C and 1H spectra.  Suitable nmr solvents Chapter 17:  Effects of hydrogen bonding on physical properties of alcohols  Acid/base properties of alcohols…similar to water  Know the ways to make alcohols.  Know the reactions of alcohols that we discussed.  Know reagents to interconvert alcohols with alkenes, alkl halides, carbonyl- containing compounds  Synthesis problems utilizing alcohols as reagents and products.  Aromatic reactions (halogenation, nitration, Friedel Crafts reactions) and their characteristics.  Grignard reagents: addition to aldehydes, ketones, formaldehyde, esters.  Effects of compounds containing active hydrogen on Grignard reagents… alcohols, amines, water, etc.
