Acetylation of Ferrocene 17. October 1996 Experiment #7 Introduction In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process had worked we employed: IR spectra analysis‚ column chromatography‚

solubility guidelines lead (II) chloride (PbCl2) is a possible precipitate. This is because even though most chlorides are soluble‚ lead chloride is considered insoluble (p.2‚ Lesson 17). Step 2: PbCl2 ↔ Pb2+ + 2Cl- Q = [Pb2+] [Cl-] 2 Step 3: Ksp = 1.2 x 10-5 (from table 17.1‚ p.5) Step 4: V2 = 20.0 mL (volume of Pb (NO3)2) + 45.0 mL (volume of CaCl2) = 65.0 mL C2 = C1 V1 V2 Looking at lead nitrate solution before being mixed with the calcium chloride solution.

Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain by a single covalent bond are called straight chain hydrocarbons. 12. Branched chain hydrocarbons

10/17/11 OUTLINE FOR REPORT ON EXP V: CHLORIDE ISE (50 points max.) I. Purpose: Use one or two complete sentences to give a concise statement of the purpose of the experiment. Experimental Parameters: Theoretical Equations: Give the theoretical equations which relate the potential of the ISE/SCE pair to the activity of chloride and the concentration of chloride. What must be true if the latter equation is to be valid? What is the ideal slope of a plot of potential versus the logarithm of the concentration

the base. H+(aq) + OH-(aq) H2O(l) When a weak acid is neutralised some of the energy is needed to dissociate the molecules to make the hydrogen ions available for neutralisation. The result is a value for neutralisation enthalpy lower than - 57 kJ/mol (numerically lower‚ not more negative!) Note that as the weak acid is in equilibrium as the hydrogen ions are ’mopped up’ by the base the equilibrium shifts to the right hand side to make more until eventually all of the acid is able to react
