At Dominican University‚ the SOC students performed this experiment during the Fall 2007 semester with not only the dehydration of 2-methylcyclohexanol (Aldrich 153087) but also the 4-methyl (Aldrich 153095) and 3-methyl (Aldrich 139734) positional isomers. The reaction products were submitted to GC-FID analysis. As predicted from the Journal of Chemical Education articles‚ three methylcyclohexene products were observed. Their relative abundance

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

Introduction Background Indicators are used in acid-base titrations to determine end points as both acid and base are colourless in nature. However‚ indicators chosen must be suitable according to the type of reactions such as: - Strong acid-weak base titration - Weak acid-strong base titration - Strong acid-strong base titration - Weak acid-weak base titration Only the first two mentioned above will be investigated in this experiment. Aims/Objectives 1. To understand

The first peak has 9.66 retention time and has one possible match out of the five which is included in appendix 1.The highest match is ecgonidine‚ methyl ester (EDME) with 944 match and a 953 reverse match. EDME is a product of the thermal decomposition of cocaine and has been identified as a likely candidate for the detection of concealed cocaine (Analytical Chemistry 1997). The second peak‚ which

When butane’s dihedral angle was at 0⁰ and 360‚ the conformations are at an Emax. This means that the two methyl groups are eclipsed. At 60⁰ and 300⁰‚ which have gauche conformations‚ the methyl groups are more shifted and the potential energy difference is 18.2 kj/mol. At 120⁰ and 240⁰‚ eclipsed again‚ the energy rises to -4.6788 kj/mol‚ from its previous -17.721 kj/mol‚ the hydrogens can be found lying on the same plane‚ increasing the energy. Yet‚ the energy is not as high as it is at 0⁰ and 360⁰
