Heroin (Mw = 369.42 g/mol) is weakly basic compound due to its tertiary amine group. The pKa of its conjugate acid form is 7.95. Six grams of a street drug containing heroin and calcium phosphate as the only components was shaken with 60 mL of chloroform. The chloroform was carefully decanted and evaporated to yield 738.84 mg of white solid, which was then dissolved in 300 mL of 6 mM HCl in water. This aqueous solution was divided into three...

Construct a flow chart describing the seperation of the
mixture and the isolation of each compound in this experiment. (Lab
steps/procedures includes for reference)
4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...

Synthesis of dimedone This lab exercise will give you practical experience with the generation of a malonic ester enolate and subsequent reaction with an a,p-unsaturated carbonyl compound. This sequence is known as the Michael reaction. In the presence of sodium methoxide, dimethyl propanedioate (malonic ester/dimethyl malonate) is converted to the corresponding enolate anion and reaction with 4-methylpent-3-en-2-one (mesityl oxide) affords the Michael adduct 1, as shown in the reaction sequence below. Under the basic reaction conditions, the Michael adduct 1...

In this laboratory exploration various reactions of copper will illustrate these properties. First, begin with copper metal. When concentrated nitric acid is added, dramatic changes occur and the metal dissolves forming a brightly colored copper ion-containing solution. Cu(s) + 4HNO3(aq) à Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l) _____________ equation Cu(s) + 4H+ + 4NO3-(aq) à Cu+2(aq) +2NO3-(aq)+ 2NO2(g) + 2H2O(l) _____________ equation Reaction type_______________ What advantage(s) is/are there to the second version of the reaction equation? However, if diluted...
