  2. All organic compounds consist of carbon and hydrogen. Many also contain oxygen and nitrogen Other elements may also be present. Phosphorous, halogens and/or metals Most compounds are composed of carbon chains bonded with hydrogen
  3. H-C-C-C-C-C-H H H H A carbon / hydrogen chain (organic) H CCC C C- A carbon / hydrogen chain containing oxygen
  4. Carbon can make four (4) bonds Hydrogen can make one (1) bond Oxygen can make two (2) bonds Nitrogen can make three (3) bonds Sulfur can make two (2) bonds Halogens can make one (1) bond -N- -c- -s-
  5. Carbon can make single, double or triplebonds Hydrogen can make only single bonds Oxygen can make single or double bonds
  6. Nitrogen can make single, double or triplebonds Sulfur can make single or double bonds Halogens can make only single bonds H- - s-c -c
  7. Naming Organic Compounds Meth = 1 C Eth = 2 C Prop But = 4 C Pent = 5 C Hex = 6 C Hept = 7 C Oct = 8 C Non = 9 C Study this Dec = 10 C Slide and then click here To continue
  8. Aliphatic Hydrocarbons Alkanes — All single bond between carbons (name ends in "ane") Alkenes — contains double bonds between carbons (name ends in "ene") Alkynes — contains triple bonds between carbons (name ends in "yne")
