**Understanding Oxymercuration-Demercuration Reaction**

Below is a question related to organic chemistry, specifically the hydroxymercuration-demercuration reaction.

### Question:
**What is the product of the following reaction?**

1. Hg(OAc)₂, H₂O
2. NaBH₄, NaOH

**Reactant:**
A branched alkene is reacting under the conditions given above.

**Possible Products:**
1. (First molecule shown) A branched alkane with an alcohol (-OH) attached at the carbon not originally part of the double bond.
2. (Second molecule shown) A branched alkane with an alcohol (-OH) attached at the middle carbon of what used to be a double bond.
3. (Third molecule shown) A branched alkane with an alcohol (-OH) attached at the terminal carbon of what used to be a double bond.
4. (Fourth molecule shown) A branched alkane with an alcohol (-OH) attached to the carbon adjacent to the branch.

The diagram lists the following:
- The reagents used are Mercury(II) acetate (Hg(OAc)₂) in water (H₂O) followed by Sodium borohydride (NaBH₄) in Sodium hydroxide (NaOH).
  
**Answer Choices:**

- The product choices are given in a visual representation, where:
  - First product: alcohol (-OH) group at terminal carbon.
  - Second product: alcohol (-OH) group at the middle carbon of the former double bond.
  - Third product: alcohol (-OH) group at the terminal carbon.
  - Fourth product: alcohol (-OH) group attached adjacent to a branch.

To solve this, understand that hydroxymercuration-demercuration is a two-step process:
1. **Hydroxymercuration**: The addition of mercuric acetate and water leads to the formation of a mercurinium ion, and a hydroxide group adds to the more substituted carbon (Markovnikov addition).
   
2. **Demercuration**: Treatment with NaBH₄ removes the mercury and replaces it with a hydrogen atom.

**Explanation of the Diagram:**
- The reactant shown is a branched alkene.
- The products shown illustrate different placements of the -OH group.

Using the concept of Markovnikov's rule, the hydroxyl group (-OH) in the product should be added to

Below are four multiple choice structural representations of different alcohols. Each option shows a distinct molecular structure with the hydroxyl group (-OH) attached to different positions on a hydrocarbon chain or framework:

1. The first structure exhibits a branched chain with the hydroxyl group (-OH) attached to the second carbon atom. 

2. The second structure displays a linear hydrocarbon chain with the hydroxyl group (-OH) attached to the terminal carbon.

3. The third structure features a branched chain where the hydroxyl group (-OH) is attached to a carbon atom that is bonded to three other carbon atoms.

4. The fourth structure has a branched chain with the hydroxyl group (-OH) attached to a carbon atom that is bonded to two hydrogen atoms and one methyl group.

Each choice is denoted by an empty circle (∘) for selection purposes. These molecular structures are essential in understanding different types of alcohols and their respective chemical properties.

For a detailed explanation of how the positioning of the hydroxyl group affects the properties and classification of alcohols, please refer to the accompanying text and diagrams on alcohol functional groups.
