AI Generated Solution

To explain the mechanism of preparing alcohols from alkenes through electrophilic attack, we can break it down into several steps: ### Step 1: Formation of the Electrophile In this reaction, we start with an alkene, which contains a double bond (C=C). The double bond consists of a sigma (σ) bond and a pi (π) bond. The π bond is rich in electrons and can act as a nucleophile. When we introduce an electrophile, such as H⁺ (proton), it will attack the electron-rich π bond of the alkene. **Hint:** Identify the electrophile and the nucleophile in the reaction. ### Step 2: Electrophilic Attack ...

Symmetrically subsituted epoxides give the same products in both the acid catalysed and base catalyzed ring opening. An unsymmetrical epoxide gives different products under acid catalysed and base catalysed conditions. Under basic contions, the alkoxide ion simply attacks the less hindered carbon atom in an SN^(2) displacement. Under acidic conditions, the alcohol, attacks the protonated epoxide. Structure II and III show that the oxtrane carbon share part of positive charge. The tertiary carbon bear a larger part of positive charge and it is more strongly electrophilic. The bond between teritiary carbon and oxygen is weaker implying a lower transition state energy for attack at the teritary carbon. Attack by the weak nucleophilic is sensitive to the strength of electrophilic is sensitive to the strength of electrophile. Center attack takes place at more electrophilic carbon which is usually the more substituted carbon because it can better support the positive charge. What will be the products in following reactions
