The best description of the role each species plays in the SN₂ synthesis of nerolin is that; I-CH₂CH₃ acts as an electrophile, the intermediate act as a nucleophile, KOH acts as base, I⁻ act as the leaving group.
The reaction takes place by the reaction of naphthol with KOH, to produce an intermediate ion of naphthol which further reacts with I-CH₂CH₃ to produce neurolin. Nerolin is an aromatic ether also called 2-ethoxynaphthalene.
From the missing image attached below, the following compounds participating in the SN₂ synthesis are as follows:
I-CH₂CH₃ (1-iodoethane): I-CH₂CH₃ acts as an electrophile because they act as an electron-deficient ion. This makes them accept electrons from nucleophiles in reaction.
Intermediate: The intermediate acts as a nucleophile because it is electron-rich and it donates electrons to the nucleophile.
KOH acts as a base because it accepts H⁺ io from naphthol.
I⁻ is the leaving group, that leaves after the reaction is complete.
Therefore, we can conclude that we understood the reaction mechanism that occurs in the SN₂ synthesis of Nerolin.
