carbon-carbon double bonds are positioned next to one another‚ a conjugated diene is formed. Conjugated dienes undergo a cycloaddition reaction with certain double bonds to afford cyclohexenes and related compounds. The reaction is named Diels-Alder. The Diels-Alder reaction is between 1‚3-butadiene and ethylene to produce cyclohexene + dienedienophile. The mechanism of the Diels-Alder reaction is classified as a [4+2] cycloaddition reaction‚ because one reactant (the diene)‚ contributes four carbon atoms

be unsaturated. Aromatic hydrocarbons are cyclic compounds whose structure is related to that of benzene‚ with six-electrons in a six-membered ring. For this experiment‚ hexane will be used as an example of saturated hydrocarbons (alkanes)‚ cyclohexene will be used as an unsaturated hydrocarbon (alkenes) and toluene as an aromatic hydrocarbon. As a precaution during these experiments‚ you should be extremely careful since these organic compounds are highly volatile (they evaporate easily) and

Experiment 1 Stereochemistry Stereochemistry is the study of the three-dimensional configuration that makes up a molecule and the ways in which this arrangement affects the physical and chemical properties of molecules. Isomerism is the main concern of stereochemistry. Isomers are sets of chemical compounds with identical molecular formulas but different structural properties. There are two types of isomers‚ structural isomers and stereoisomers. Structural isomers are subdivided into two:

bromine solution is added then the reaction would not be able to run to completion and bromine would be the limiting reagent causing less final product. (c) If cyclohexane was used then it would not react with the bromide nearly as much as the cyclohexene and there would be a larger amount of bromide in the final

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

Chem 205 I. Title and Equation: Unimolecular Elimination + 2 Isomers II. Experimental Procedure : In a flask‚ 0.081 mol of 2-methycyclohexanol and 3 mL of 85% H3PO4 were mixed. The mixture was boiled under a fractional distillation column‚ and 7 mL of the distillate was collected. The organic and aqueous layers were separated and the organic layer was dried with anhydrous sodium sulfate. The product was analyzed using GC. III. Conclusion: In this experiment‚ 2-methylcyclohexanol
