Question

For the following reactions, fill in the boxes with the predominant product or products. You must indicate stereochemistry with wedges and dashes. If a racemic mixture is created, you must write "racemic" under the structures.

**Title**: Reaction Mechanism and Stereochemistry Analysis **Text**: **Problem 2**: For the following reaction, fill in the box with the predominant product or products. You must indicate stereochemistry with wedges and dashes. If a racemic mixture is created, you must write "racemic" under the structures. **Reaction Details**: - **Reactant**: The structure on the left side of the arrow is 2-methyl-2-butene, a branched alkene. - **Reagent**: HBr (Hydrobromic acid) is added to the alkene. **Instructions**: - Determine the product(s) of the reaction. - Identify and draw the major product with correct stereochemistry: - Show any chiral centers using wedges and dashes to indicate the three-dimensional arrangement. - If the reaction yields a racemic mixture, be sure to label it as "racemic" below the structures. **Key Concepts**: - The reaction involves the addition of HBr to the alkene, typically following Markovnikov's rule, where H is added to the less substituted carbon, and Br to the more substituted carbon. - Consider the formation of carbocation intermediates and any possible rearrangements. - Analyze the stereochemistry to establish if the product is obtained as a single enantiomer or a racemic mixture. This exercise helps in understanding the principles of regioselectivity and stereochemistry in electrophilic addition reactions.
