Show Answer
Solution:
- In the given question, the substrate is a $2^{\circ}$-halide (bromide) and the medium, $CH _3 OH$ (as well as a poor nucleophile) is protic in nature, So, the reaction will follow mainly $S _N 1$ pathways via the formation of a carbocation intermediate (I).
The intermediate, I can be rearranged into the more stable form I’ $\left(3^{\circ}\right)$ by $\alpha$-hydride shift. I ’ will give the major product.
