Question

Add curved arrows to the reactant side of the following Sn1 mechanism.

Add curved arrows to the reactant side of the following SN1 mechanism.

Answer 1

Concepts and reason

S_N1 reaction is a nucleophilic substitution reaction. Here, the number 1 indicates unimolecular. This reaction occurs in two steps. In the first step, the leaving group dissociates from the substrate and forms a carbocation. In the second step, the attacking nucleophile attacks on the carbocation to from the product.

Fundamentals

S_N1 stands for substitution, nucleophilic, unimolecular. In S_N1 reaction, one nucleophile is substituted by another nucleophile. It is a two-step reaction.

The rate of the reaction depends only on the concentration of substrate. It does not depend on the concentration of incoming nucleophile.

A nucleophile is a molecule or ion that can donate an electron pair.

Part 1

The curved arrow mechanism for the first step is as follows:
