Question1:
In acidic conditions epoxides can be protonated. Protonated epoxides can undergo ring opening in the presence of poor nucleophiles. In these reactions the nucleophile preferentially attacks the more substituted carbon atom of the epoxide, as shown in the example below. Explain why the nucleophile preferentially attacks the more substituted carbon atom of the epoxide in acidic conditions. OCH3 он CH3 H3C CH3 H3C minor product major product

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,...
