**Predict whether this reaction would display rearrangements.**

**Chemical Reaction:**

A chemical structure is displayed on the left. It consists of a benzene ring attached to a three-carbon chain with a double bond at the end. Below the structure, the reagents Br₂ and H₂O are indicated, pointing downward with an arrow.

**Options:**

- **A)** Rearrangements are never observed in this general type of reactions.
- **B)** Rearrangements can be observed in this general type of reactions and this substrate would rearrange.
- **C)** Rearrangements can be observed in this general type of reactions but this substrate would not undergo rearrangements.

**Explanation:**

The diagram presents a typical structure undergoing reaction with bromine (Br₂) in the presence of water (H₂O). The task is to determine whether this particular reaction will involve rearrangements in its mechanism. The options provide possibilities regarding the occurrence of rearrangements.

**Title: Understanding the Major Product Formation in Hydroboration-Oxidation**

In this exercise, you are tasked with identifying the major product of a specific chemical reaction, while ignoring any inorganic byproducts.

**Reaction Overview:**

- **Starting Material:** A hydrocarbon structure consisting of a double bond and a branched alkyl group.
- **Reaction Conditions:**
  1. **Reagents:** Mercuric chloride (Hg(Cl)₂) in methanol (CH₃OH)
  2. **Reagents:** Sodium borohydride (NaBH₄) in sodium hydroxide (NaOH)

**Transformation:**
- **Initial Steps:** The alkene undergoes a reaction with Hg(Cl)₂ in methanol, which typically involves a mercuration step forming an intermediate organomercury compound.
- **Final Steps:** This intermediate is then reduced using NaBH₄ in the presence of NaOH, commonly leading to the formation of a hydroxyl group.

**Major Product:**
- The major product depicted in the diagram is an alcohol, formed by the addition of a hydroxyl group (OH) to the more substituted carbon of the initial double bond structure, resulting from the Markovnikov addition in the oxymercuration-demercuration process.

**Diagram Explanation:**
- The resultant structure is represented with the OH group attached to the most substituted carbon atom, typical of this reaction mechanism.

This type of reaction is essential for understanding the conversion of alkenes to alcohols, frequently utilized in organic synthesis for creating functionalized molecules.
