Organic compounds continued

  1. 1. Organic Compounds continued…<br />8SCIENCE: Thurs. Feb. 3/ Fri. Feb. 4<br />
  2. 2. Review: What is an organic compound?<br />Organic compound is anything with carbon in it<br />What is a hydrocarbon?<br />Compound that contains only hydrogen and carbon<br />What are the two types of hydrocarbons?<br />Saturated<br />Unsaturated <br />
  3. 3. Substituting hydrocarbons<br />We can remove H atoms from C and substitute or replace these with a different element:<br />Example: Cl – chlorine, Br – bromine<br />We take off the H atoms and replace with Cl<br />Trichloromethane:<br />
  4. 4. Functional groups<br />We can also replace the H (hydrogen atoms) with a GROUP of elements, called functional groups<br />Each group changes the function and characteristics of the hydrocarbon<br />4 types to learn:<br />OH<br />COOH<br />NH₂<br />NH₂ and COOH<br />
  5. 5. Functional groups<br />
  6. 6. Polymers<br />If we put many of these organic compounds together, it is called a POLYMER<br />Example: many amino acids bonded together creates a protein, which are important for all living things, including plant reproduction and processes<br />How does this relate to plants?<br />Plants make carbohydrates (sugars) for its food energy<br />Carbon, oxygen and hydrogen are combined to make the compound, carbohydrates<br />Many of these small “building blocks” of atoms are combined to create a polymer  carbohydrates!<br />
  7. 7. Organic compounds = “molecules for life”<br />Why are these compounds called “molecules for life”?<br />Plants create these organic compounds <br />These are nutrients that plants and other organisms need for their health and to survive <br />
