Correct Separation Scheme

* cannot be hand drawn

*see attached image of "incorrect separation scheme"

Illustrate a correct separation scheme to isolate your molecule (2,6-dimethyloct-2-ene) 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.

· 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
