Base promoted 1,2 elimination is an important way to synthesize alkenes from alkyl halides or alcohols. reaction of 2-bromo-3,3-dimethylbutane with dilute solution of sodium ethoxide and ethanol proceeeds by first order reaction with the generation of three isomeric alkenes in significant yields. Propose a likley mechanism to explain for the first order reactioon and the production of compounds. Give the IUPAC names of the alkenes.
