Experiment: Comparing reactivities of alkanes and alkenes Aim: To compare the reactivities of an alkane and an alkene with bromine water and a solution of potassium permanganate (KMnO4). Equipment: • 4 test tubes • Test-tube rack • 4 pipettes Safety: safety glasses must be worn to prevent injury to the eyes. Ensure room is well ventilated whilst using the hydro carbons. Method: 1. Place 1 ml of sample A (cyclohexane) into a test tube containing 4 mls of the bromine water solution. Record

The Michael addition is a reaction named after Arthur Michael. Discovered in 1887‚ this is a carbon-carbon bond making reaction. The result of the Michael addition is a 1‚4 addition of a nucleophile to an alpha‚ beta-unsaturated carbonyl carbon compound. A 1‚4 addition is also commonly referred to as a conjugated addition. Another result of this reaction is a 1‚2 addition of a nucleophile. Some of the common attacking nucleophiles used in this reaction are enolates. Enolates‚ a negatively charged

Introduction In this experiment‚ exo-norborneol was produced by a hydration of alkenes by using an acid and excess water. Hydration of alkenes is the acid-catalyzed addition of water to a carbon-carbon pi bond that leads to the formation of an alcohol. Norbornene is a bridged cyclic hydrocarbon‚ this molecule contains a double bond that induces significant ring strain‚ and therefore‚ it is highly reactive. In order for this reaction to occur‚ equilibrium must be established between the hydration

Positive and negative effects of winning the lottery Winning the lottery is something everyone wants. Rarely do people realize that there are also bad effects to having such a large sum of money. A good amount of people that win the lottery are foolish with their money‚ quit their jobs‚ or just don’t know what to do with it. The others that win make smart decisions in either investing their fortune‚ donating it to a good cause‚ or just helping their family be finically stable. Majority of people

Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

Jacobsen’s Method of Epoxidation of an Alkene | | Abstract Various types of reactions were completed to first create and then use Jacobsen’s catalyst in the asymmetric epoxidation of an unknown alkene with bleach in the laboratory. The chiral epoxide synthesized was then characterized with GC/MS and NMR. With this information the unknown alkene was able to be identified as 4-chlorostyrene. Introduction Organisms have evolved with mechanisms that use specific enantiomers of molecules
