$(CH_3)_3CO^{-}$

Vedclass · Answer

(C) The substrate is $2-bromo-2-methylbutane$. Elimination can occur to form the more substituted alkene $(I)$ (Zaitsev product) or the less substituted alkene $(II)$ (Hofmann product). To obtain the less substituted alkene $(II)$ as the major product,a bulky base is required to minimize steric hindrance during the abstraction of the less hindered proton. $(CH_3)_3CO^{-}$ (potassium tert-butoxide) is a bulky base and is known to favor the formation of the Hofmann product.

Consider the following reaction. Which of the following bases will give the best yield of the alkene $(II)$ as the major product?
