Dehydrohalogenation of 2-bromo-2-methylbutane with a sterically bulky base like potassium tert-butox — Reaction Mechanism Chemistry Question
Question
Dehydrohalogenation of 2-bromo-2-methylbutane with a sterically bulky base like potassium tert-butoxide ($t-BuO^-$) predominantly yields:
Answer: B
💡 Solution & Explanation
A bulky base cannot easily access hindered internal protons. It abstracts the exposed terminal protons, yielding the kinetically controlled, less substituted Hofmann alkene.
