Radical Chlorination of 1-Chlorobutane. The radical chlorination of 1-chlorobutane was carried out using sulfuryl chloride and azoisobutyronitrile (AIBN). From the reaction there were for possible products which are as follows 1,1-dichlorobutane, 1,2- dichlorobutane, 1,3-dichlorobutane, and 1,4-dichlorobutane. The structures produced from the reaction are as follows; Attached to the four carbons in 1-chlorobutane are hydrogens that can react readily with chlorine, because of its electron withdrawing character. Chemical environment surrounding the carbons are different and therefore affecting the character of the hydrogens attached.

This is done by a procedure called refluxing. Refluxing is the process of heating a product to the boiling point and re-condensing the vapor continuously. The procedure halogenation is the addition of a halogen to a π bond forming a halo alkane. In this synthetic reaction bromine was used in the process called bromination. The bromine is acting first like an electrophile, and then after bromine has broken the π bond, a carbocation has formed, and a bromide ion has been created, the bromide ion then acts as the nucleophile and forms a bond with the carbocation.
Introduction: The radical chlorination of chlorobutane results in the formation of four possible products. These products are formed by substitution reactions, where a halogen atom (chlorine) replaces a hydrogen atom (Wade 2010). The amount of each product formed is based on the relative reactivity of the product. The calculations of the relative reactivity are dependent on the reactivity of the hydrogen atoms, which is influenced by the chloro substituent as well as other factors such as the level of the substituted carbon and the bond dissociation energy. For this lab we want to observe how the chloro substituent has an effect on the reactivity of the possible hydrogen atoms.
Introduction High performance liquid chromatography (HPLC) is used to separate compounds in a sample, identify compounds and can even be used to deduce the relative amounts of different compounds in a mixture. HPLC works under the same principle as thin layer chromatography using both a stationary and mobile phase. The mobile phase carries the mixture across the stationary phase which is used to separate the compounds. Although in HPLC mobile phase is tailor made to suit the polarity of the analytes. The mobile phase used in this particular experiment was Methanol and 0.1M sodium dihydrogen phosphate at a ratio of 30:70 and a pH of 4.5, slightly acidic.
Double displacement reaction: Chemical reactions in which one component each of both the reacting molecules is exchanged to form the products. 3. What does the stoichiometry of a chemical reaction mean? Why is it important? Stoichiometry is a section of chemistry that involves using the relationships between reactants or products in a chemical reaction to determine the desired quantitive data.
How it was expected the pH at equivalence point was 9.17 this is because of the domination of hydroxide ion in solution. The relationship between the pH and the amount of titrant added offered a better understanding of the equilibrium properties of the acid. Introduction Titrations are a convenient and common method of analysis. Generally titration is an experiment where a known property of one solution is used to infer an unknown property of another solution. There are several types of titrations: Acid-base titrations are based on the neutralization reaction between the analyte and an acidic or basic titrant.
Two ionic compounds often react so that the positive and negative ions change places. For example, AgNO3 and NaCl will react to form AgCl and NaNO3. Predict the results of the reaction between barium carbonate and magnesium sulfate. Write the formulas and the names of the reactants and products. 3.
Water samples from the Clark Fork have been taken and will be tested using both absorption and emissions spectroscopy in order to check the levels of group IA and IIA metal ions. When electrons in an element are excited energy is released that can be measured as light. Each element releases different levels of energy that are observed as different wavelengths of light. With the proper equations (E=hv and E=hc/⋋), emission spectroscopy can be used to find the wavelength and frequency of light emitted by the excited electrons. This will help determine the types of ions present in the water sample.
