Organic Chemistry Study Guide; Exam 4 (Fall 2007) AIC CHAPTERS 8, 9, 10, 11 I. Reactions: 1. Addition Reactions (addition to alkenes and alkynes) Ionic additions: ENu adds to C=C or C C E: H + , X + , HgOAc + , B Nu: :Nu - = X - , O-SO 2 -OH - HNu: = HO-H, R-OH C C E-Nu C C C C E E-Nu C C E Nu Nu Look Out for Rearrangements Note: Addition of H 2 O requires the presence of H + and Hg +2 . 2. Addition of O atoms to alkenes and alkynes: (a) 1,2- diol formation (syn addition). Use KMnO 4 (aq) (25 o C, pH = 7) or OsO4 followed by reduction with NaHSO3. (b) Oxidative cleavage: (1) with O 3 , followed by H 2 O/Zn. (2) hot KMnO 4 /OH - (followed by H + (aq) ) 3. SYN vs. ANTI Addition - Page 3 of this document, last section. II. Mechanisms : Be able to write a stepwise mechanism for each of the following 1. Addition of HX , X 2 , (X 2 + H 2 O) to alkenes. 2. Addition of HX or H 2 O to alkene which involves rearrangement of carbocation intermediate. I. Reactions: Predict organic product(s) of given reaction OR provide missing reactant in given equation. If a specific stereoisomer is formed (or reacts), be able to draw a 3D formula
