Elimination Flashcards
Is E1 one or two step reaction?
Two step
proceeds through carbocation formation
Is E1 unimolecular or biomolecular and give me a bit of knowledge on the reaction rate?
Unimolecular
Reaction rate depends on substrate
Is E1 1st or 2nd order reaction?
1st order reaction
what is the rate equation of E1?
Rate = k[alkyl halide]
what does E1 prefer, tertiary carbocation or tertiary alkyl halides?
Tertiary carbocation
What solvent does E1 need?
Polar protic solent needed
does E1require a strong base?
it does not
What is the stereochemistry of E1?
Prefers E-isomers, less steric hindrance equal major product
Is E2 unimolecular or biomolecular? and would you be so kind to share a nugget of knowledge about the reaction rate?
Biomolecular
Rate depends on concentration of both substrate and base
is E2 one or two step?
one step mechanism
Base picks up acidic proton from B carbon
is E2 1st or 2nd order reaction?
2nd order reaction
what is the rate equation for E2?
Rate = k[alkyl halide][base]
what does E2 prefer, Tertiary alkyl halides or tertiary carbocation?
Tertiary alkyl halides
what does E2 solvent prefer?
prefers polar aprotic solvents so it does not form hydrogen bonds with the base
eg. dnso, acetonenitrile
is a strong base need by E2?
it is needed
