organic chemistry

• Alkenes are hydrocarbons that contain at least one double bond between two carbons, while alkynes have triple bonds.
• homologous series

  
  

  members of homologous series have same general formula

  same functional group

  similar chemical properties

  a gradation in physical properties differs by ch2 unit or 14 units mass different
• hydrocarbon - carbon and hydrogen containing compounds
• hydrocarbons contain 3 groups

  Alkanes, Alkenes, Alkynes
• Alkanes are saturated hydrocarbon, single boned hydrocarbon
• Alkenes and Alkynes are unsaturated hydrocarbons
• general equation- CnH2n+2
