Interpretation Introduction

Interpretation:

To draw the carbocation intermediate that is expected when the fallowing alkyl chloride under ionization process has to be identified.

Concept Introduction:

${\text{S}}_{\text{N}}\text{1}$Reaction: It is a nucleophilic substitution reaction in which the rate determining step depends on one reactant. First step is the formation of more stable carbocation which is followed by the attack of nucleophile. Formation of more stable carbocation and the leaving group present in the substrate plays very important role in the reactivity of ${\text{S}}_{\text{N}}\text{1}$ reaction. The increasing stability order of carbocation is as follows,

Primary carbocation < secondary carbocation < tertiary carbocation

Carbocation: it is carbon ion that bears a positive charge on it.

Leaving group: it is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.

Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.
