The first step involves the reaction of 1-bromo-2,2-dimethylpropane (I) with NaNH2, which is an elimination reaction leading to the formation of 2,2-dimethylpropene (II). The second step involves the reaction of II with HBr, which is an addition reaction leading to the formation of 2-bromo-2-methylpropane (III). The third step involves the reaction of III with sodium methoxide (NaOCH3), which is an elimination reaction leading to the formation of 2-methylpropene (IV). The major product obtained from the given sequence of reactions is IV, since it is the only compound shown in the answer choices.
