2-Bromo-2-methylbutane is heated with $(CH X_{3}) X_{3} COK$ in $(CH X_{3}) X_{3} COH$ . The major alkene is

A2-methylbut-2-ene
B3-methylbut-1-ene
C2-methylbut-1-ene
Dpent-2-ene

Answer: C

The bulky base removes the more accessible hydrogen from the

CH X_{3}

group, giving the less substituted Hofmann alkene 2-methylbut-1-ene. With a small base such as ethoxide the Saytzeff alkene 2-methylbut-2-ene would predominate.
