**Question:**(b) The product or products of the reaction are characterized as being- [ ] achiral- [ ] R, S (and/or S, R)- [ ] S- [ ] S, S- [ ] diastereomers- [ ] R, R- [ ] R- [ ] racemic **Educational Content on Alkene Hydroboration-Oxidation****Introduction:**Alkenes can undergo a transformation to become alcohols through the process of hydroboration-oxidation. This reaction sequence is significant in organic chemistry for its ability to convert double bonds into alcohols with specific stereochemistry.**Reaction Details:**1. **Reactant:** The starting material is an alkene. The structure shown is cyclohexene, which features a six-membered carbon ring with a double bond.2. **Reaction Conditions:** - **Step 1:** The alkene is treated with borane (BH₃) in the presence of diglyme (a solvent). This step is known as hydroboration, where boron adds across the double bond. - **Step 2:** The boron-containing intermediate is reacted with hydrogen peroxide (H₂O₂) and hydroxide ions (OH⁻) in water. This stage, known as oxidation, replaces boron with a hydroxyl group, converting the alkene into an alcohol.**Instructions for Representation:**- **Structure Drawing:** When depicting the alcohol product, clearly indicate stereochemistry using bond representations: - **Wedge Bond:** Represents a bond coming out of the plane towards the viewer. - **Dash Bond:** Represents a bond going into the plane away from the viewer. - **In-plane Bonds:** Used for bonds lying flat in the plane of the drawing.- **Hydrogen Atoms:** Ensure to draw hydrogen atoms connected to the chiral centers or as specified in the chemical structure.**Diagram Explanation:**The diagram illustrates the chemical reaction of cyclohexene (hexagonal structure with a double bond) undergoing conversion to the corresponding alcohol. The reagents are listed alongside arrows indicating the sequence of steps involved in the transformation.**Conclusion:**This hydroboration-oxidation process is crucial for obtaining alcohols with controlled stereochemistry from alkenes, a fundamental transformation in organic synthesis. Understanding this reaction helps in predicting the outcome and configurations of organic compounds in chemical research and industry.
