Context

Organic halides are organic compounds that contain one or more halogen atoms (fluorine, chlorine, bromine, or iodine) bonded to carbon atoms. The nomenclature, that is, the way we name these compounds, follows specific rules established by the International Union of Pure and Applied Chemistry (IUPAC).

In everyday life, organic halides are frequently found in various contexts. Although they are used in a variety of industrial applications, the misuse of organic halides can lead to environmental and health problems.

For example, some organic halides have been widely used in the industry as refrigerants, aerosol propellants, cleaning solvents, and fire extinguishers. However, when released into the atmosphere, these compounds can contribute to the degradation of the ozone layer.

In the field of medicine, organic halides play an important role as anesthetic and antibacterial agents. Nevertheless, many of them are highly toxic and can lead to a range of health problems if not handled properly.

Therefore, understanding the structure and nomenclature of organic halides is essential for chemistry students. This project aims to broaden the understanding of these compounds, develop research skills and teamwork, and enhance the ability to comprehend and apply nomenclature rules.

The following resources can be used as a basis for the project and to deepen knowledge on the subject:

Practical Activity

Activity Title: "Discovering the Nomenclature of Organic Halides"

Project Objective

Students will be challenged to research and identify the nomenclature of different organic halides, reflecting on their different properties and applications.

Detailed Project Description

Groups of 3 to 5 students must create an "Organic Halides Deck of Cards." Each card in this deck should present a different organic halide, with its respective name, molecular structure, and a brief description of its practical application or importance.

Each group must create 20 different cards, totaling the presentation of 20 organic halides. The halides presented cannot be repeated among the cards.

After creating the deck, the groups must hold an "Organic Halides Tournament," where they will be encouraged to ask each other questions about the nomenclature and functions of the halides present on the cards in their decks.

Required Materials

• Research in books, reliable websites, or scientific databases.
• A4 paper for making the cards.
• Printer (optional)
• Colored pens, pencils, markers, etc.

Detailed Step-by-Step

1. Students must form groups of 3 to 5 members.

2. Each group should research different organic halides, focusing on the structure, nomenclature, and application of each one. They should choose 20 different halides for each group.

3. Students need to create an "Organic Halides Deck of Cards." Each card in this deck should present a different organic halide. Each card should include:

   • Name of the organic halide.
   • Molecular structure of the halide.
   • A brief description of its use or importance.

4. After creating the deck, the groups will hold an "Organic Halides Tournament." In this tournament, each group will ask questions to others about the nomenclature, structure, and functions of the halides present on the cards in their decks.

Project Deliverables

• Organic Halides Deck of Cards: The physical deck must be submitted to the teacher, and a digital copy of the cards must be made available to classmates.

• Written Document: Each group must prepare a detailed report on the activity. The report should cover the following topics:

  1. Introduction: Where students should contextualize the importance and applications of organic halides and the objective of this project.

  2. Development: Students must explain the theory of organic halides, describe the assembly of the deck, and the tournament, indicate the methodology used, and finally present and discuss the results obtained.

  3. Conclusion: Recapitulate the main learnings, with an emphasis on understanding the nomenclature, structure, and functions of the organic halides studied.

  4. Bibliography: Indicate the research sources used for the project.

The written document should be a minimum of 3 pages and a maximum of 5 pages. It must be submitted in digital format (preferably in .docx or .pdf).
