Verified step by step guidance

Understand the types of reactions: E1, SN1, E2, and SN2 are all types of nucleophilic substitution or elimination reactions in organic chemistry. Each has distinct characteristics and mechanisms.

Consider the mechanism of E1 reactions: E1 reactions are unimolecular elimination reactions that proceed through a two-step mechanism involving the formation of a carbocation intermediate. This intermediate can lead to a slower reaction due to its stability and the time required for its formation.

Compare with SN1 reactions: SN1 reactions are unimolecular nucleophilic substitution reactions that also involve a carbocation intermediate. Like E1 reactions, the formation of the carbocation can slow down the reaction.

Evaluate E2 and SN2 reactions: E2 reactions are bimolecular elimination reactions that occur in a single concerted step, typically faster due to the absence of intermediates. SN2 reactions are bimolecular nucleophilic substitution reactions that also occur in a single step, generally faster than SN1 and E1 due to the direct attack of the nucleophile.

Conclude which reaction is slower: Given the mechanisms, E1 reactions often take longer to reach completion compared to E2 and SN2 reactions due to the formation and stability of the carbocation intermediate.
