Draw the major product for each of the reactions, showing the correct stereochemistry, if any.

Draw hydrogen atoms on chirality centers.

### Reaction A The diagram illustrates a chemical reaction involving a cyclohexane derivative. The reactant is a cyclohexane ring with two substituents: a hydroxyl group (OH) and a hydrogen atom (H) on adjacent carbons. Both substituents are depicted using wedge-and-dash notation to indicate their stereochemistry. The hydroxyl group is shown as a wedge, indicating it is coming out of the plane toward the viewer, while the hydrogen atom is on the same carbon as a dashed line, indicating it is going away from the viewer. The chemical reaction involves the addition of hydrobromic acid (HBr), as shown by an arrow pointing toward the right. This suggests the formation of a new compound through a substitution or addition reaction involving the HBr and the cyclohexane derivative. The specific details of the product are not depicted in this diagram.

The diagram depicts a two-step chemical reaction involving a cyclohexane derivative. **Structure on the Left:** - A cyclohexane ring with an alcohol group (OH) attached to one carbon. The carbon with the OH also has two hydrogens attached, one in the plane (solid line) and one as a wedge (pointing downward). **Reaction Steps:** 1. **First Step:** TosylCl (tosyl chloride) with pyridine. - This step typically involves converting the alcohol (OH) group into a better leaving group, often generating a tosylate. 2. **Second Step:** NaBr (sodium bromide). - This step generally involves a nucleophilic substitution where Br⁻ (bromide ion) replaces the tosylate group, leading to the formation of a bromo-cyclohexane derivative. **Overall Reaction Overview:** - The reaction involves the conversion of the hydroxyl group into a bromine atom via a tosylate intermediate. This sequence is useful for substituting alcohol groups with other nucleophiles.
