Study Guide for Exam on Ch 24 - 26 McMurry

Ch 24
Know the preparation, reactions, nomenclature and property trends for amines. You may skip the spectroscopy section 24.10 (old 24.9) for now and problems 24.63-.65 (old 24.52-.53). Problems 24.43, .49-.50, .52, .54, .61-.62 and .66 (old 24.29, .35-.38, .45, .47, & .50-.51) are the more difficult. (Note to old book users: ch 25 contains the Sandmeyer reactions, which are in ch 24 in the 5th edition.)

Ch 25
On p. 1035 (old  p. 1015) know structures of D-glyceraldehyde, D-glucose, D-ribose and D-fructose, and know the other names on p. 1037 (old p.1017.)  Know also the structures of maltose, cellobiose, and lactose disaccarides and the differences between cellulose and starch. You should understand the glycoside structures in general. Be able to draw and recognize Fischer and Haworth projections and be able to go back and forth between them, and chair conformers. Know the reactions (except for chain lengthening and shortening) and all terminology.   Skip problem 25.40 (old 26.38.)

Ch 26
Know the names of the amino acids on pp 1076-1077 (old pp 1058-1059) and the structures of alanine, cysteine, glycine, leucine, phenylalanine and serine.  Be able to use the isoelectric point to explain behavior of amino acid in various pH media. You do not have to be able to synthesize amino acids.  You should understand the process for building peptide chains (in a lab) but you don't have to know all the reactions used.  Also understand the structural features which arise due to sequence, H-bonding, disulfides, etc.

Exam 4

The format of the exam will be: First pages - mechanisms you write out details on the mechanisms of Aldol, Claisen (ch 23),  Hoffman elimination or degradation or Sandmeyer reaction  (ch 24) and some of the amino acid questions could be here.  Multiple choice - reactions, properties (basicity, acidity, etc.), miscellaneous  Matching on Scantron - reactions in a "map" like I do on the board sometimes, and which are related to synthesis problems in philosophical approach. Reactions from these chapters integrated together. (30 pts)
