1. Hydrogen (H): Hydrogen is extremely common in organic compounds. It often bonds with carbon to form hydrocarbons, which are the building blocks of many organic molecules.
2. Oxygen (O): Oxygen is crucial for many organic functions. It's present in alcohols, ethers, aldehydes, ketones, carboxylic acids, and many other important organic compounds.
3. Nitrogen (N): Nitrogen is a key component of amino acids, the building blocks of proteins. It's also found in many other organic molecules like amines, amides, and nucleotides (which make up DNA and RNA).
