Organic Sample with Hydrochloric Acid and Sodium Hydroxide

  1. Aug 23, 2008 #1
    I am confused with how these reaction occurs. I don't know the
    polarity of compunds like NaHCO3, Amyl acetate, Benzoic Acid, Phenol, and Ethylamine


    Organic Sample with 1M HC with 1M NaOH with NaHCO3
    Amyl acetate insoluble insoluble X
    Cyclohexane insoluble insoluble X
    Ethylamine miscible miscible X
    Ethanol soluble soluble X
    Benzoic Acid(solid) insoluble soluble soluble(effervescence)
    Phenol immiscible miscible insoluble(no bubbles)

    why is it the organic sample reacted with the HCl and NaOH and NaHCO3 in that
    manner?

    What's the distinction here between soluble and miscible ; are they both homogenous? What's with the "X"? My guess is that the organic sample is not acidic or basic since their is no change in dissolution in solvents with no significant acidic or basic groups.

    The Organic samples listed are observed if there are any reactions with HCl, NaOH and NaHCO3

    Describe the scope of this experiment e.g. procedures.

    test the solubility of each compound by adding 1ml of 1M HCl. Repeat using 1ml of 1M HCl.

    test amyl acetate with 1M HCl and 1M NaOH
    test cyclohexane with 1M HCl and 1M NaOH
    test ethylamine with 1M HCl and 1M NaOH
    test trimethyl amine with 1M HCl and 1M NaOH
    test ethanol with 1M HCl and 1M NaOH
    test bezoic acid with 1M HCl and 1M NaOH and NaHCO3
    test phenol with 1M HCl and 1M NaOH and NaHCO3

    Well in general if the organic sample can be protonated or deprotonated this increases the ionic character and thus the partition coefficient in favor of water.
