Chapter 13, Problem 60a
What alkene could you use to make the following products? Draw the structure of the alkene, and tell what other reagent is also required for the reaction to occur.
a. 
Verified step by step guidance1
Step 1: Understand the reaction type. The problem involves identifying the alkene and reagent needed to produce a specific product. This suggests a reaction mechanism such as an addition reaction, where an alkene reacts with a reagent to form the product.
Step 2: Analyze the product structure. Examine the product (represented by the image) to determine the functional groups and connectivity of atoms. Look for features such as hydroxyl groups, halogens, or other substituents that indicate the type of addition reaction.
Step 3: Work backward to deduce the alkene. Remove the added groups (e.g., halogens, hydroxyls) from the product to reconstruct the original alkene structure. This is the reverse of the addition reaction.
Step 4: Identify the reagent. Based on the functional groups added to the product, determine the reagent required. For example, if the product contains a hydroxyl group, the reagent might be water (H₂O) in the presence of an acid catalyst. If a halogen is present, the reagent could be a halogen molecule (e.g., Br₂ or Cl₂).
Step 5: Draw the structure of the alkene and specify the reagent. Represent the alkene using a structural formula and clearly state the reagent needed for the reaction to occur. Ensure the structure aligns with the product and reaction mechanism.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Alkenes
Alkenes are hydrocarbons that contain at least one carbon-carbon double bond (C=C). They are unsaturated compounds, meaning they have fewer hydrogen atoms than alkanes with the same number of carbon atoms. Alkenes are reactive and can undergo various chemical reactions, including addition reactions, where other atoms or groups are added across the double bond.

Addition Reactions
Addition reactions are a type of chemical reaction where two or more reactants combine to form a single product. In the context of alkenes, these reactions often involve the addition of halogens, hydrogen, or water across the double bond. Understanding the specific conditions and reagents required for these reactions is crucial for predicting the products formed from a given alkene.

Reagents
Reagents are substances that are added to a chemical reaction to cause a change or to facilitate the reaction. In the case of alkenes, common reagents include hydrogen (for hydrogenation), halogens (for halogenation), and acids (for hydration). Identifying the correct reagent is essential for determining the products of the reaction and understanding the mechanism involved.
