Benzene is stable to both Br2 / CCl4 and KMnO4 / -OH. Therefore‚ there is something unusual about the double bonds in benzene‚ the unsaturation is atypical / unique 2. Benzene undergoes substitution rather than addition reaction‚ i.e.‚ Br Br Br2 + HBr FeBr3 Br Addition product not observed This observation is contrary to that of unsaturated aliphatic compounds e.g. alkenes. Benzene is far more stable than typical alkenes 3 3. Benzene gives only ONE monosubstituted product

Bacani‚ and Steven Arthur Baluyot Analysis of Hydrocarbons Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract In this experiment we performed parallel chemical test method to identify an unknown. The reflux setup was used to prevent evaporation in mixing the reactants in an inert solvent with its boiling point. Another highlight of this experiment is the liquid-liquid extraction wherein a solution containing

Maleic anhydride underwent the Dials-Alder reaction with distilled cyclopentadiene as the dienophile. The reaction was a cycloaddition which produced cis-Norbornene-5‚6-endo-dicarboxylic Anhydride surface. (1) Product one had a mass of 9.351 grams and product two had a mass of 9.572 grams. The theoretical yield was found to be 10.047 grams‚ which makes the percent yield to be 93.07%. Melting Points were found to confirm the purity of the product. Product one had a melting point of 163.7-164
