Organic Chemistry reactions

• Structural isomers is when molecules have the same molecular formula (same number and type of atoms) but different atom to atom bonding .
• Empirical Formula 


  Chemical formula showing the simplest ratio of atoms in a compound (Sometimes the same as molecular formula)
• Molecular Formula 


  Chemical Formula showing the exact number of elements in a compound.
• Condensed Structural Formula 


  Showing the grouping/order of the atoms in a compound.
• Expanded Structural Formula 


  EVERYTHING
• Skeletal Formula


  Covalent bonds are shown as lines and symbols for all elements other carbon and hydrogen are always shown.
• Naming (what comes first?) = alcohol, alkene, halo, methyl
