Organic Chemistry: are these answers correct?

In summary, the conversation is about a series of chemical reactions involving different reagents and substrates. The first part discusses the use of Br2 and H3O+ followed by a Gilman reagent, while the second part mentions the use of Br2 with light, t-BuO-, and HBR. The last part involves the use of CH3O- and HCl in two steps, with a rearrangement and intramolecular reaction. Some additional remarks are made regarding the possibility of a Michael's addition and the importance of adding the carbonyl ketone later to prevent self-condensation reactions.

What I got:

5. a. Br2 and H3O+. Then a Gilman reagent of (PhCHCHCH2)2CuLi followed by THF.

5. b. First Br2 w/ hv. Then t-BuO- and finally HBR with ROOR.

5. c. CH3O- and HCl (two step), rearrangement, more CH3O- / HCl and then intramolecular reaction.

Just some remarks

1)may be a michael's addition?

2)You would probably have the attack on the carbonyl ketone, which is added later to prevent self-condensation reactions.

I am unable to determine whether your answers are correct without more context. What is the topic or question that these images are related to? Are you referring to a specific reaction or reaction mechanism? Additionally, without knowing the specific conditions and reagents used, it is difficult to determine the correctness of your answers. It is important to provide all relevant information when discussing organic chemistry reactions and mechanisms.
 

1. What is organic chemistry?

Organic chemistry is the branch of chemistry that studies the structure, properties, and reactions of carbon-based compounds, also known as organic compounds. It involves the study of the structure, composition, and properties of these compounds and how they interact with each other and with other substances.

2. Why is organic chemistry important?

Organic chemistry is important because it is the foundation for understanding the chemical processes that occur in living organisms. It is also essential for the development of new medicines, materials, and technologies.

3. What are some common topics studied in organic chemistry?

Some common topics studied in organic chemistry include the structure and properties of organic compounds, organic reactions, organic synthesis, and the use of organic compounds in various industries such as pharmaceuticals, materials, and agriculture.

4. How is organic chemistry different from inorganic chemistry?

Organic chemistry is different from inorganic chemistry because it focuses on the study of carbon-based compounds, while inorganic chemistry focuses on the study of compounds that do not contain carbon. Additionally, organic compounds are typically more complex and have a wider range of structures and properties compared to inorganic compounds.

5. What are some real-world applications of organic chemistry?

Organic chemistry has numerous real-world applications, such as the development of new medicines, the production of plastics and polymers, the synthesis of new materials, and the production of food and agricultural products. It is also used in the development of new technologies and products in various industries, including cosmetics, textiles, and electronics.
