Once you have separated the compounds, identifying them is a puzzle for you to solve the melting point, ir, nmr, and even appearance of each compound are clues about their identity we provide you with a list of possible unknown compounds (this situation reflects some real-world organic laboratory synthetic. Experimental learning objectives: at the end of this experiment you should be able to: (i) use a separatory/dropping funnel (ii) dry an organic liquid (iii) use a rotary evaporator (iv) identify the organic phase in an immiscible organic/ aqueous mixture (v) use acid/base reactions to impact the solubility of organic compounds.
Most nonvolatile solid organic compounds can be analyzed by tlc to carry out a tlc experiment, a small amount of the mixture being separated is dissolved in a suitable solvent and applied or spotted on the adsorbent near one end of a tlc plate the plate is then placed in a closed chamber with the edge nearest the.
