* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

Now wash (microscale) the combined extracts with saturated NaCl solution (5mL)‚ then with 10% aqueous potassium carbonate (5mL)‚ then with saturated NaCl solution (5 mL) again. Dry the organic layer with anhydrous sodium sulfate. Decant the organic layer into a small beaker and concentrate to roughly 0.2 mL by evaporation in the hood (do not apply heat!). If the sample goes to dryness‚ re-dissolve in hexane (0.2 mL). *Set aside a small amount of your crude
