The correct Answer is:
To analyze the statements provided, we need to understand the reaction of propene with HBr in the presence of organic peroxides and the mechanism involved. ### Step-by-Step Solution: 1. **Understanding the Reaction**: - Propene (C3H6) is an alkene that can react with hydrogen bromide (HBr). - In the presence of organic peroxides, this reaction follows a different mechanism compared to the usual electrophilic addition. 2. **Mechanism of Reaction**: - Normally, the addition of HBr to alkenes proceeds through a carbocation intermediate. The double bond attacks the H from HBr, forming a carbocation, which is then attacked by the Br- ion. - However, in the presence of organic peroxides (like H2O2), the reaction follows a radical mechanism instead of forming a carbocation. 3. **Radical Mechanism**: - The presence of peroxides generates free radicals that initiate the reaction. - The reaction proceeds via the formation of bromine radicals, which add to the double bond of propene, leading to the formation of 1-bromopropane (instead of 2-bromopropane, which would be formed via the carbocation pathway). 4. **Conclusion**: - **Statement-1** is true: Propene reacts with HBr in the presence of organic peroxide to give 1-bromopropane. - **Statement-2** is false: The reaction does not occur through a carbocation intermediate; it proceeds through a radical mechanism due to the presence of organic peroxides. ### Final Answer: - Statement-1 is true. - Statement-2 is false.
