Fundamentals of Organic Molecules
Introduction

Organic chemistry is the study of compounds that contain carbon. Carbon is a versatile element that can form a wide variety of bonds, which makes it possible for organic molecules to have a vast array of structures and properties.


Key Points

  • Organic molecules are composed of carbon, hydrogen, and often other elements such as oxygen, nitrogen, sulfur, and phosphorus.
  • Carbon has four valence electrons, which allows it to form four covalent bonds.
  • The arrangement of atoms in an organic molecule is called its structure.
  • The properties of an organic molecule are determined by its structure.
  • Organic molecules can be classified into different types based on their structure and properties.

Main Concepts

  • Covalent bonding: Organic molecules are held together by covalent bonds, which are formed when atoms share electrons.
  • Structural isomerism: Organic molecules with the same molecular formula can have different structures. These different structures are called isomers.
  • Functional groups: Functional groups are groups of atoms that have specific chemical properties. The presence of a functional group in an organic molecule can greatly influence its properties.
  • Organic reactions: Organic molecules can undergo a variety of chemical reactions, which can be used to synthesize new organic molecules.

Conclusion

Organic chemistry is a vast and complex field, but the fundamentals of organic molecules are relatively simple. By understanding the basic concepts of organic chemistry, you can gain a deeper understanding of the world around you.


Experiment: Separation of Organic Compounds by Paper Chromatography

Objective: Demonstrate the separation of organic compounds based on their relative polarities and partition coefficients using paper chromatography.


Materials:



  • Coffee filter paper or chromatography paper
  • Solvent (e.g., methanol, dichloromethane)
  • Capillary tubes or micropipettes
  • Unknown organic compounds
  • Ruler
  • UV lamp (optional)

Procedure:



  1. Draw a starting line about 2 cm from the bottom of the filter paper.
  2. Using a capillary tube or micropipette, spot small amounts of each unknown organic compound along the starting line, making sure to leave enough space between spots.
  3. Suspend the filter paper in a chromatography chamber filled with the solvent so that the bottom edge of the paper is immersed in the solvent.
  4. Cover the chamber and allow the solvent to migrate up the paper.
  5. When the solvent front reaches the top of the paper, remove it from the chamber and mark the solvent front.
  6. Measure the distance each compound traveled from the starting line to its center (Rf value).
  7. Calculate the Rf value for each compound using the formula: Rf = Distance compound traveled / Distance solvent front traveled
  8. Identify the unknown compounds by comparing their Rf values to known standards.

Key Procedures:



  • Ensure the filter paper is not overloaded with sample.
  • Use a fresh filter paper for each experiment.
  • Allow the solvent to migrate at a constant rate by adjusting the solvent level in the chamber.
  • Handle the filter paper carefully to avoid tearing.

Significance:


Paper chromatography is a valuable technique for separating and identifying organic compounds. It is widely used in fields such as forensic science, pharmaceuticals, and environmental analysis. By understanding the principles of paper chromatography, students can gain insights into the behavior of organic molecules and their interactions with different solvents.
