Question

Identify major product formed in the following reaction. 3-Bromo-2-methylpentane $\xrightarrow{Alc.KOH}$ Major product}

• A. 2-Methylpentan-3-ol
• B. 2-Methylpent-2-ene
• C. 4-Methylpent-3-ene
• D. 4-Methylpentan-3-ol

Hint:

In E2 elimination reactions with alcoholic $KOH$, the major product is generally the most substituted alkene according to Zaitsev's rule. This means the hydrogen is removed from the beta-carbon with the fewest hydrogen atoms, leading to a more stable, more substituted double bond.
