Elimination

These flashcards cover essential vocabulary and concepts related to elimination reactions of alkyl halides in organic chemistry.

E1 Reaction

An elimination reaction that is unimolecular, where the rate depends on the concentration of the alkyl halide.

E2 Reaction

An elimination reaction that is bimolecular, involving the simultaneous removal of a hydrogen and halide from adjacent carbon atoms.

Alkene Stability

The stability of alkenes increases with greater substitution; more substituted alkenes are generally more stable.

SN1 Reaction

A substitution reaction that is unimolecular, favored in tertiary substrates; involves the formation of a carbocation.

SN2 Reaction

A substitution reaction that is bimolecular, favored in primary substrates; involves a backside attack leading to a concerted mechanism.

Bimolecular Elimination (E2)

A mechanism where two species are involved in the rate-determining step, leading to an alkene formation.

Unimolecular Elimination (E1)

A mechanism that occurs in two steps, first forming a carbocation followed by deprotonation to create the alkene.

Trans (E) Alkene

A configuration of an alkene where the highest priority substituents are on opposite sides, resulting in lower stability compared to cis isomers.

Primary Substrate

A substrate where the carbon bearing the leaving group is attached to only one other carbon.

Tertiary Substrate

A substrate where the carbon bearing the leaving group is attached to three other carbons, preferentially undergoing elimination in SN1/E1 conditions.
