Verified step by step guidance

Understand the concept of nucleophilic substitution reactions. These reactions involve the replacement of a leaving group by a nucleophile. They are characterized by the attack of a nucleophile on an electrophilic center, typically a carbon atom bonded to a leaving group.

Identify the types of nucleophilic substitution reactions. The two main types are SN1 and SN2 reactions. SN1 reactions are unimolecular nucleophilic substitutions, while SN2 reactions are bimolecular.

Examine the given options: Diels-Alder reaction, SN1 reaction, E2 reaction, and E1 reaction. Note that the Diels-Alder reaction is a cycloaddition reaction, not a nucleophilic substitution.

Recognize that the SN1 reaction is a nucleophilic substitution reaction. It involves a two-step mechanism where the leaving group departs first, forming a carbocation intermediate, followed by the nucleophile attacking the carbocation.

Differentiate between substitution and elimination reactions. E2 and E1 reactions are elimination reactions, where a molecule loses atoms or groups, forming a double bond, rather than substituting a nucleophile.
