Contextualization

Organic Chemistry is one of the most fascinating branches of chemistry, with applications in numerous areas of human knowledge. A very important chemical reaction in this context is the addition reaction, which involves the addition of two or more reagents to a multiple bond. Addition reactions form the basis for many industrial chemical processes, such as the production of plastics, medicines, fuels, and many others.

Addition reactions are common in organic compounds containing double or triple bonds. They occur when two or more atoms or groups of atoms join atoms that were linked by a multiple bond, breaking this bond and forming new single bonds. These types of reactions are fundamental for the formation of many complex organic compounds.

In this project, we will explore addition reactions - their mechanisms, products, and applications. For example, the addition reaction of hydrogen to ethylene, resulting in ethane, is a typical example of an addition reaction that we will study.

Importance of Addition Reactions

Now that we understand what an addition reaction is and how it works, let's discuss why it is important. The ability to form new compounds through addition reactions is crucial in the production of a variety of materials we use in our daily lives.

Plastics, for example, are produced through addition reactions. The same goes for many medicines, which are synthesized through addition reactions to complex organic compounds. In short, addition reactions play a fundamental role in organic chemistry and the chemical industry, making our daily lives more comfortable and convenient.

Practical Activity: Unraveling Addition Reactions

Project Objective

This project aims to explore the concept of addition reactions in organic chemistry and understand their importance in our daily lives. Students will work in groups of 3 to 5 members and will have one week to complete the project.

Detailed Project Description

Students will be challenged to create an educational and illustrative guide on addition reactions. This guide should include clear and detailed explanations of addition reactions, examples of such reactions, and their practical applications. In addition, students must conduct research to learn more about a common product in our daily lives that is produced through addition reactions, and include this in their guide.

Required Materials

1. Paper and pencil to sketch ideas.
2. Computers with internet access for research.
3. Text editing software (Microsoft Word, Google Docs, etc).
4. Slide creation software (Microsoft PowerPoint, Google Slides, etc).
5. Drawing materials for illustrations (optional).

Detailed Step-by-Step

1. Group Formation: Students must form groups of 3 to 5 members.

2. Research and Study: The group must conduct a detailed research on addition reactions and their practical applications. The research should be focused, but not limited, to addition reactions in organic compounds containing double or triple bonds.

3. Guide Development: The group must work together to create an educational guide on addition reactions. This guide should clearly explain what addition reactions are, provide concrete examples, and discuss their practical applications.

4. Selection of a Product: The group must select a common product in our daily lives that is produced from addition reactions and include a detailed description of how addition reactions are involved in this product in their guide.

5. Writing the Written Document: After completing the practical part of the project, students must cooperatively write a document with Introduction, Development, Conclusions, and Bibliography used.

Project Deliverables

At the end of the project, students must deliver:

1. The Educational Guide: An illustrative and well-written guide on addition reactions. This guide should be clear, informative, and visually appealing.
2. Written Document: A detailed project report containing:
   • Introduction: Contextualization of the theme and project objectives.
   • Development: Detailed explanation of the activities carried out, description of the theory behind addition reactions, exemplification of the methodology used, and presentation and discussion of the results obtained.
   • Conclusions: Recap of the main points of the project, statement of learnings, and conclusions about the work done.
   • Bibliography: The sources of information used for the project.
