Solution

Solution Steps

Step 1: Analyze the Reaction Conditions

The reaction involves 1-chloro-5-methyl-2-hexene and methanol ($\mathrm{CH}_3\mathrm{OH}$). Methanol is a polar protic solvent, which typically favors $\mathrm{S}_\mathrm{N}1$ and E1 mechanisms due to its ability to stabilize carbocations.

Step 2: Determine the Likely Mechanism

Given the presence of a polar protic solvent and a secondary alkyl halide (1-chloro-5-methyl-2-hexene), the $\mathrm{S}_\mathrm{N}1$ mechanism is more likely than $\mathrm{S}_\mathrm{N}2$. The $\mathrm{S}_\mathrm{N}1$ mechanism involves the formation of a carbocation intermediate, which is stabilized by the solvent.

Step 3: Identify the Major Product

In the $\mathrm{S}_\mathrm{N}1$ mechanism, the carbocation formed can be attacked by the methanol, leading to the substitution product. The major product of this reaction would be 1-methoxy-5-methyl-2-hexene.
