Provide the Major product for the following addition reactions

### Chemical Reactions of Alkenes This image displays three distinct alkene reactions, showcasing different reagents and conditions leading to various products. 1. **Reaction with HBr and Peroxide (ROOR)** - **Reactant:** An alkene with the structure CH₃-CH(CH₃)-CH=CH₂. - **Reagents:** Hydrogen bromide (HBr) and a peroxide, often abbreviated as ROOR. - **Description:** This reaction represents the anti-Markovnikov addition of HBr to the alkene. The presence of peroxide initiates a radical mechanism, resulting in the bromine atom adding to the less substituted carbon of the double bond. 2. **Reaction with Bromine (Br₂)** - **Reactant:** The same alkene, CH₃-CH(CH₃)-CH=CH₂. - **Reagent:** Bromine (Br₂). - **Description:** When alkenes are treated with Br₂, bromine adds across the double bond in an anti-addition fashion, forming a vicinal dibromide. The reaction is typically conducted in an inert solvent like dichloromethane. 3. **Reaction with Hydronium Ion (H₃O⁺)** - **Reactant:** A cyclohexene structure with a single double bond (C₆H₁₀). - **Reagent:** Hydronium ion (H₃O⁺). - **Description:** This reaction involves the acid-catalyzed hydration of the alkene, where water adds across the double bond. This reaction follows Markovnikov's rule, resulting in the formation of an alcohol. The hydronium ion serves as a catalyst, promoting the reaction through a carbocation intermediate. These reactions are fundamental to understanding electrophilic addition mechanisms in organic chemistry, demonstrating how different reagents influence the regioselectivity and stereochemistry of addition to alkenes.
