Certainly! Let's analyze the problem step-by-step. --- ## Step 1: Understand the reactant The given structure is **phenol**: - It consists of a benzene ring (aromatic ring). - Attached to the benzene ring is a **hydroxyl group (-OH)**. **Chemical structure:** ``` OH | Benzene ring ``` --- ## Step 2: Identify the type of reaction The reaction involves **HBr (hydrobromic acid)**, which typically reacts with compounds containing functional groups such as alcohols. **Key points:** - Phenol's hydroxyl group is attached to an aromatic ring. - Phenol is more acidic than typical alcohols because the phenolate ion (the conjugate base) is stabilized by resonance. --- ## Step 3: Reactivity of phenol with HBr **Phenol** can undergo **bromination** in the presence of acids like HBr, especially under suitable conditions, leading to **bromination at the ortho and/or para positions** relative to the hydroxyl group. --- ## Step 4: Major product of bromination - The hydroxyl group **activates** the benzene ring towards electrophilic substitution. - The **ortho and para positions** are most activated. Given that HBr is used, the bromine acts as an electrophile, leading to substitution at the **para position** typically because: - The para position is less hindered. - Under controlled conditions, para-bromophenol is the major product. --- ## **Final step: Draw the major product** ### Structure: - The phenol ring with a bromine atom substituted at the **para position** relative to the hydroxyl group. ### Drawing: ``` Br | Benzene ring with -OH at position 1 ``` The substituents: - **OH group** at position 1. - **Bromine (Br)** at position 4 (para position). --- ## **Summary:** - The major product is **4-bromophenol**. - **Structure:** Phenol with a bromine atom at the para position. --- ## **Final answer:** **The major product is 4-bromophenol.**
