Organic Chemistry
2
Organic Compounds Organic Compounds – A compound containing Carbon and Hydrogen The most common elements in living things are: Carbon Hydrogen Oxygen Nitrogen All organic compounds contain CARBON & HYDROGEN Common Organic Compounds: Carbohydrates Lipids Proteins Nucleic Acid
3
Organic = has Carbon (C ) and Hydrogen (H)
Organic or Inorganic??? Organic = has Carbon (C ) and Hydrogen (H) Inorganic Inorganic H2O C6H12O6 CO2 NaCl CH4 C12H22O11 ClO2 C10H14N2 HCl NaOH C18H12 C9H13NO Organic Organic Inorganic Inorganic Inorganic Inorganic Organic Organic Organic Organic
4
Types of Carbohydrates
Monosaccharide – 1 sugar molecule Disaccaride – 2 sugars bonded together Polysaccaride – 3 or more sugars bonded together Polymers – large molecules consisting of chains of repeating units
5
Types of Carbohydrates
Mono = 1 Di = 2 Poly = 3 or more
6
Natural Polymers
7
Proteins – natural polymers
Proteins – used to build and run an organism’s body Amino Acids – structural units of proteins; only 20 different types Sequence of amino acids = Protein
8
Nucleic Acids – Natural Polymers
Nucleic Acid – hereditary material that is passed on from one generation to the next during reproduction; directs and controls the development and activities of all cells Contains a 5-carbon sugar, phosphorous group and a nitrogen base Kinds of Nucleic Acids: Deoxyribonucleic Acid (DNA) Ribonucleic Acid (RNA)
9
Nucleic Acid
11
Synthetic Polymers Plastic Nylon Teflon Polyester
PVC - polyvinyl chloride PET - polyethylene terephthalate
12
Saturated vs. unsaturated
13
Hydrocarbons and hydrocarbon derivatives
Hydrocarbons are compounds that contain only carbon and hydrogen in their formulas. Two basic categories of hydrocarbon: Saturated hydrocarbons: all carbon atoms are connected together with single bonds Unsaturated hydrocarbons: involve one or more multiple (double, triple) C-C bonds
14
Alkanes: saturated hydrocarbons
16
Alkanes: saturated hydrocarbons
CH4 C2H6 C3H8
17
Unsaturated hydrocarbons
Hydrocarbons which contain at least one C-C multiple (double or triple) bond. Alkenes are unsaturated, acyclic hydrocarbons that possess at least one C-C double bond. The generic formula for an alkene is CnH2n
