1. (a) Alkanes are saturated hydrocarbons.explain the words saturated and hydrocarbons. (b) Alkanes are generally unreactive. Explain why this is so. (c) write balanced equations for the complete combustion of: (i) methane (ii) ethane. 2. Use the passage below and your knowledge to answer the questions that follow. Methane reacts with bromine to give bromomethane and hydrogen bromide. The mechanism for the reaction is called free-radical substitution and involves

SYNT 0719 – Brominating Alkenes OBJECTIVE The purpose of this lab will be to brominate trans-stilbene by using acetic acid and pyrimidium tribromide by refluxing the mixture. To test the purity of product I will take the melting point which should be around 240 ºC along with a flame test which should be green-blue. CHEMICAL PROPERTIES TABLE See Attached Lab Notebook Copies REACTION MECHANISM In this lab we used multiple techniques to complete and verify the bromination of trans-stilbene

The carcinogenic nature of N-nitrosamines depends on the organs. For example‚ their targets for cancer in rodents include thyroid‚ pancreas‚ urinary bladder‚ trachea‚ lung‚ oral and nasal cavities‚ esophagus‚ kidney and liver. With respect to N-nitrosamides‚ skin‚ bone‚ peripheral nervous system‚ brain‚ small intestine and glandular stomach are targeted organs for cancers. Besides cancer‚ acute myelocytic leukemia and T and B cell lymphoma have also been triggered by N-nitrosamides. In table 8.1

The Friedel-Crafts acylation reaction created acetylferrocene and diacetylferrocene‚ using phosphoric acid as a catalyst for the reaction between acetic anhydride and ferrocene (once applying heat). During column chromatography‚ a solution is passed through a filtration system

mixing an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks‚ and the rearrangement of alkyl carbocation electrophile (McMurry). Acylation reactions require molar amounts of a Lewis catalyst‚ in our case Aluminum Chloride (AlCl 3) was used (Arata‚ Nakamura‚ & Shouji). Materials and Methods Reflux

To investigate stereochemistry of bromination reaction Introduction Alkenes undergo electrophilic addition to give alkyl halides. When bromine is used as a reagent‚ the reaction proceeds via 2-‐step process. The first step involves the

is very reactive as it more nucleophilic. Nucleophiles are compounds negatively charged in other word positive charge loving that donate their pair of electrons to form a new bond. They can also be called Lewis bases as they accept proton from electrophilic species. Grignard reagent can be simply prepared by redox reaction of magnesium metal and alkyl halide in dry diethyl ether solvent. In this experiment the alkyl halide use is bromobenzene‚ to form the reagent phenylmagnesium bromide. Figure
