When 2-bromo-2-methylbutane is treated with a base, a mixture of 2-methyl-2-butene and 2-methyl-1-
butene is produced. When potassium hydroxide is the base, 2-methyl-1-butene accounts for 45% of the
product mixture. However, when potassium tert-butoxide is the base, 2-methyl-1-butene accounts for
70% of the product mixture. What percent of 2-methyl-1-butene would be in the mixture if potassium
propoxide were the base?
