Here's a more detailed explanation:Carbon (C): All organic compounds contain carbon. Hydrogen (H): Most organic compounds also contain hydrogen. Other Elements: Organic compounds can also contain other non-metals like oxygen (O), nitrogen (N), sulfur (S), or phosphorus (P). Identifying Elements:Chemical Formula: Examine the chemical formula of the compound. For example, ethanol (C₂H₆O) clearly shows carbon, hydrogen, and oxygen. Structural Formula: Look at the structural formula to see which elements are bonded together. Periodic Table: If you are unfamiliar with the elements' symbols, use the Periodic Table to identify them.
