Your answer is partially correct. Try again Although both 1-bromobutane and 4-bromo-1-butene are primary halides, the latter undergoes elimination more rapidly. How can this behavior be explained? but-2-ene The product formed when 1-bromobutane undergoes elimination is a simple monosubstituted alkene J. when 4-bromo-1-butene undergoes elimination, the product is relative stablites of the products. Since but-1,3-ene a conjugated dieneand therefore, a more stable # product. The transition states leading to the products reflect the the transition state leading to 1,3-butadiene has...

The dehydration of alcohols Under acidic conditions, alcohols will undergo a dehydration reaction, producing an alkene and water. During the reaction, the hydroxyl group of the alcohol and a hydrogen atom from an adjacent carbon atom are lost. The reaction takes place in three steps, as shown in the diagram. (Figure 1) In the first step, a hydrogen lon bonds to the hydroxyl group of the alcohol. In the second step, the protonated hydroxl group leaves the compound,...
