# Chemical Reaction Product Prediction **Objective:** Draw the main product you expect from each reaction below. Pay attention to stereochemistry. --- ### Reaction 1: **Starting Material:** A bicyclic compound with three methyl (Me) groups attached to the ring. **Reagent:** \[ \text{Br}_2, \text{hv} \] This reaction involves bromination using light (hv), which typically leads to free radical substitution at the most stable location in the organic structure. --- ### Reaction 2: **Starting Material:** A cyclobutane ring with two hydroxyl (OH) groups on adjacent carbon atoms in the chain. **Reagent:** \[ \text{H-Br (2 equiv)} \] The reaction with HBr (two equivalents) generally suggests conversion of alcohols to alkyl bromides, likely by a substitution mechanism. --- **Note:** Consideration of stereochemistry is crucial for accurately predicting the products of these reactions.

The image depicts two separate chemical reactions involving alcohols. 1. **First Reaction:** - **Reactant:** A cyclohexanol derivative with a hydroxyl group (OH) attached to a cyclohexane ring. - **Reagent:** Thionyl chloride (SOCl₂) in the presence of a base. - **Condition:** SN2 reaction mechanism is assumed. - **Outcome:** The hydroxyl group is likely replaced by a chlorine atom, resulting in the formation of a chlorocyclohexane. 2. **Second Reaction:** - **Reactant:** A secondary alcohol with a methyl group (Me) substituent. - **Reagent:** Hydrochloric acid (HCl). - **Outcome:** The hydroxyl group is protonated and replaced by a chlorine atom, likely forming a different chloroalkane via nucleophilic substitution. These reactions demonstrate common transformations of alcohols into alkyl halides under acidic and neutral conditions, highlighting mechanisms like SN2 for stereochemistry inversion and nucleophilic substitution through protonation.
