Contextualization

Organic chemistry is a vast field of study on compounds that contain carbon atoms. One of these compounds known as Organic Halide is one that has one or more halogens (F, Cl, Br, I) attached to a carbon atom. In many universities and schools, this section of organic compounds is superficially addressed, or even ignored, despite its enormous relevance in the world of science.

The study of organic halides is of fundamental importance, as these compounds are used as reagents in various organic reactions, such as nucleophilic substitutions, eliminations, additions, among others. In addition, organic halides have practical applications as solvents, refrigerants, fire extinguishing agents, and in medicines.

Understanding the nomenclature of these compounds is essential for chemists, as it provides the basis for the structural identification of chemical substances. The nomenclature for these compounds is based on the rules of IUPAC (International Union of Pure and Applied Chemistry), which is the organization that governs chemical nomenclature. It stipulates clear and systematic rules that allow chemical structures corresponding to chemical names to be clearly defined.

In this project, we will explore the world of organic halides in an engaging and fun way, through a didactic and practical project. In addition to learning about the nomenclature of these compounds, students will be challenged to work together, using their logical and creative skills to solve problems and create solutions.

Atividade Prática: "Exploring the World of Organic Halides"

Project Objectives

1. Understand the core concepts about the composition, classification, and nomenclature of organic halides.
2. Develop teamwork, communication, research, and problem-solving skills.
3. Connect theoretical content with the real world, identifying practical applications of organic halides.

Detailed Project Description

Students will be divided into groups of 3 to 5 members. Each group will have the task of exploring a specific subset of organic halides (alkyl halides, aryl halides, aliphatic halides, aromatic halides). They will research, develop, and present a multifaceted project that includes:

1. Theoretical research: The group will research and discuss in-depth the properties, nomenclature, and uses of their specific subset of organic halides. They must understand the IUPAC rules for the nomenclature of organic halides and be able to explain them to a lay audience.

2. Connection with the real world: The group will investigate and present where and how their specific subset of organic halides is used in industry, medicine, research, or other areas of real life.

3. Practical activities: The group will design, execute, and document one or more simple and safe experiments that illustrate one or more properties or uses of their specific subset of organic halides.

Required Materials

Books, articles, internet access for research; it is recommended that students work on sets of molecules to understand the structure and nomenclature. They will also need basic laboratory material if they decide to perform a practical experiment.

Detailed Step-by-Step

1. Divide students into groups of 3 to 5 students.
2. Distribute the subsets of organic halides among the groups.
3. Instruct students to research deeply about the subset of organic halides assigned to them, focusing on properties, nomenclature, and uses.
4. If students decide to perform a practical experiment, help them plan and execute the experiment safely.
5. After completing the research and practical activities (if any), students should gather to record their findings and reflections in a report.

Project Deliverables

Each group will have to produce a detailed report of their project, which should be structured as follows:

1. Introduction: In this section, the group must contextualize the topic, explaining what organic halides are, why they are important, and what the objectives of their project are.
2. Development: Here, the group must detail their theoretical research, explaining the properties, nomenclature, and uses of the subset of organic halides assigned to them. They must also describe in detail any practical experiments they conducted, including the methodology used, the results obtained, and their interpretations of those results.
3. Conclusion: The group must conclude the work by summarizing their main points, stating the learnings obtained, and the conclusions drawn from the project.
4. Bibliography: The group must list all sources used in their research. This includes books, articles, websites, and any other materials they used to obtain information.

Students will be evaluated based on the quality of their research, the depth of their understanding of the topic, the creativity and effectiveness of their practical experiments (if any), and the quality of their final report.
