Reaction Mechanisms
A reaction involving the loss of a leaving group followed by nucleophilic attack, often forming a carbocation intermediate.
What is an SN1 reaction
functional group containing a carbonyl bonded to at least one hydrogen
What is an aldehyde
CH₃CH₂OH
What is ethanol
Sharp peaks in an IR spectrum tell you what?
What is a functional groups
Which mechanism favors a tertiary substrate and a polar protic solvent?
What is SN1
What is the slowest step in an E1 or SN1 reaction?
What is the formation of the carbocation
This group defines alcohols
What is a hydroxyl group
The prefix "cyclo" means
What is the molecule contains a ring structure (or has six carbons)
NMR splitting tells you this about a proton
What is the number of neighboring protons
Which reaction is concerted and involves backside attack?
What is SN2
In two step substitution mechanisms, what most determines whether the reaction follows an SN1 pathway instead of SN2?
What is the stability of the carbocation intermediate
Name a functional groups that contains oxygen
What are alcohol, ether, ester, or carboxylic acid
Name:CH₃CH₂CH(CH₃)CH₂OH
What is 2-methyl-1-butanol
What are the IR and NMR peaks you would see for an alcohol?
IR: broad OH at ~3300; NMR: singlet ~1-5 ppm for OH proton
IR: OH at ~3300 and NMR singlet ~1-5 ppm
What factors favor an SN2 mechanism over SN1?
Primary substrate, strong nucleophile, polar aprotic solvent (name any of the ones)
