TERM 1 Alkene ---(H-X)----> DEFINITION 1 Alkyl halide -H and -X added Carbocation intermediate-1,2-shift is possible Regioselective- Markovnikov's Rule Not stereoselective- if new chiral center forms, both configurations are possible TERM 2 Alkene ---(H2O/H3O+)----> DEFINITION 2 Alcohol -H and -OH added Carbocation intermediate- 1,2-shift possible Regioselective- Markovnikov's rule Not stereoselective-if new chiral center forms, both configurations are possible TERM 3 Alkene ---(X2)----> DEFINITION 3 Alkyl dihalides -X and -X added Onium ion intermediate- 1,2-shift not possible Not regioselective Stereoselective- anti addition TERM 4 Alkene ---(X2/H2O)----> DEFINITION 4 Halohydrin -X and -OH added Onium ion intermediate- 1,2-shift not possible Regioselective- (-Br adds to the less substituted C, -OH adds to the more substituted C of onium ion) Stereoselective-anti TERM 5 Alkene ---(1. Hg(OAc)2, H2O 2) NaBH4/ -OH)--- > DEFINITION 5 Alcohol -H and -OH added Onium ion intermediate- 1,2-shift not possible Regioselective- Markovnikov's rule Stereoselective- anti addition TERM 6 Alkene ---(1. BH3/THF (solvent) 2.H2O2/NaOH)----> DEFINITION 6 Alcohol -H and -OH added Regioselective- Non-Markovnikov Stereoselective- syn addition TERM 7 Alkene ---(1. OsO4 2.NaHSO3)----> DEFINITION 7 Vicinal Diols -OH and -OH added Not regioselective stereoselective- syn addition TERM 8 Alkene ---(1. O3 2. (CH3)2S)----> DEFINITION 8 Carbonyl carbons Split the C=C in half, and make each of the C=C carbons a carbonyl carbon TERM 9 Alkene---(H2/Pd)----> DEFINITION 9 Alkane -H and -H added Not regioselective Stereoselective- syn TERM 10 Alkyne ---(1. X2 2.CH2Cl2)----> DEFINITION 10 Tetrahaloalkane -X and -X added twice Onium ion intermediate- 1,2-shift not possible Not regioselective- 2nd -Br adds to more sub. C of onium ion Not stereoselective
