Interpretation Introduction

Interpretation:

The accomplishment of the curved arrow pattern should be identified for the given transformation.

Concept introduction:

Substitution reaction: During a chemical reaction when one functional group is transformed as another functional group in a chemical compound is called substitution reaction.

Nucleophilic Substitution reaction: electron rich nucleophile attacks the positive or partially positive charge of an atom and replace a leaving group is called Nucleophilic Substitution reaction.

$S_{N}1$reaction: The $S_{N}1$ reaction is twostep process, leaving group leaves the molecule is first step and forms the more stable carbocation. Further, nucleophile attacks the carbocation and forms the final product in the second step. The rate of the reaction depends on the stability of the carbocation.

$S_{N}2$reaction: The $S_{N}2$ reaction is single step process, leaving group leaves the molecule and nucleophiles attack the molecule is single step process which is simultaneous process.

Elimination reaction: An elimination reaction is removal of two substituents in a molecule and forms alkene. An elimination reaction is one or two-step process which based on the mechanism when two substituents removed from the molecule in single step is called E1 reaction. When two substituents are removed from the molecule in two steps is called E2 reaction.
