In the butadiene series, what causes the Amax value of the para-nitro phenyl case to be higher than that of the methoxy phenyl case? What is the main difference in electron delocalization between a compound with a dimethylamino phenyl substituent and the compound with a methoxyphenyl substituent of a particular stilbene series?

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? base Br A. Less than 45% B. C. 45% Between 45% and 70% D. More than 70%
