Question

On a page titled Correct Separation Scheme print/draw a correct separation scheme to isolate your molecule from the provided second molecule. Make sure to indicate the phase of each chemical in every step (s, l, g, aq) and write the separation technique used in each step (ie: vacuum filtration). The list below gives the reagents available in the lab. Use any of the reagents below to isolate the compounds. Remember that the simplest separation scheme is the best one. Try to avoid unnecessary steps. (reagents available: 10% aqueous NaOH H2O 5% aqueous NaHCO3 H3PO4 6M HCl anhydrous Na2SO4 5% HCl anhydrous MgSO4 Diethyl ether (ether) Saturated NaCl CH3OH Sodium borohydride (NaBH4) lithium aluminum hydride (LiAlH4) NaCl solid).        Separation scheme between: (2,6 - dimethyloct -2- ene and 4-chloro - 3 methyl- pent -2- enylamine).

2,6-dimethyloct-2-ene

Explanation / Answer

Separation scheme

1) put both compounds in an organic solvent say dichlormethane

2) Add 5M HCl to it. 4-chloro-3-methyl-pent-2-ethylamine forms a hydrochloride salt and goes in water.

3) Separate the aqueous layer and neutralize it by adding 10% aqueous NaOH to it. the amine reprecipitates out. separate the amine by filtration.

4) The organic layer is dried over anhydrous MgSO4 and vaccum filtered to separate the MgSO4 from it. Solvent is removed to isolate 2,6-dimethyloct-2-ene.
