Document Summary

Ochem textbook notes chapter 17: aldehydes and ketones. 17. 1 naming the aldehydes and ketones carbonyl function is the highest ranking group: aldehyde takes precedence over ketones, but not over carboxylic acids. Aldehydes: suffix aldehyde or al: simple/common suffix ic or oic acid ketones: suffix ketone or one. Number the chain starting with the carbonyl carbon. Polarization alters the physical constants of aldehydes and ketones: makes boiling points higher. Hydrogens of aldehydes are very strongly deshielded (between 9-10 ppm: because movement of pi electrons causes local magnetic field that strengthens the external field. Also, the positive carbon exerts additional deshielding effect. C13 nmr spectra: both aldehydes and ketones appear at 200 ppm, lower field because of electronegative oxygen: carbons next to carbonyl group are also deshielded relative to those farther away. Marko(cid:448)(cid:374)iko(cid:448)"s rule in which hydrogens attack the less substituted carbon: anti-markovnikov addition observed in hydroboration-oxidation, friedel-crafts acylation (15-13): 17. 5 reactivity of the carbonyl group: mechanisms of addition.
