Exam 2

Steric Hindrance a decrease in reactivity from the presence of bulky groups at the site of a reaction
Does steric hindrance decrease nucleophilicity AND basicity? No, basicity is not decreased by steric hindrance
polar protic solvents capable of intermolecular hydrogen bonding. They contain either O-H or N-H
Cations and anions can both be solvated by protic/aprotic solvents? Protic
Cations are solvated by... ion-dipole interactions
Anions are solvated by... hydrogen bonding
Nucleophilicity (increases/decreases) as you go down a column for polar protic solvents increases. this is opposite of basicity
Polar aprotic solvents exhibit dipole dipole interactions but can't hydrogen bond. solvate only cations
In polar aprotic solvents nucleophilicity (increases/decreases) as bascitiy increases increases
SN1 stands for substitution nucleophilic unimolecular (two step)
SN2 stands for substitution nucleophilic bimolecular (one step)
concerted reaction bond breaking adn bond making occur at the same time
frontside attacks (retain/change) configuration? retain
backside attacks (retain/change) configuration? change
frontside and backside attacks result in enantiomers/diasteriomers? enantiomers
all SN2 reactions are front/backside? backside attack
