Aliphatic compounds Nonaromatic hydrocarbons such as alkanes‚ alkenes or alkynes 2. Aromatic compounds A series of cyclic unsaturated compounds with unusually high stability • The properties and reactions of aromatic compounds are exemplified / demonstrated by the properties and reactions of benzene (the “parent”

The formation of product cyclohexene which is reweight and adding of bromine the last reagent for confirming that is alkene known as bromine test which leads to colour changes. Yet this experiment reflects some important discussion and conclusion for the formation of cyclohexene. INTRODUCTION One of the common ways of preparing an alkene is through the dehydration of an alcohol. Cyclohexanol‚ the reagent of this experiment‚ is used in the production of nylon‚ paints‚ plastics

bond. Both of the reactants are non-polar but there is an induced polarity during the reaction due to the electron-rich site at the double bond‚ which results in bromine acting as an electrophile. In this reaction‚ the cinnamic acid reacts as an alkene. Alkenes are unsaturated hydrocarbons with a carbon-carbon double bond. In a double bond‚ a pair of electrons lies between the carbon atoms in a σ bond and the other pair of shared electrons lie above and below the plane in a π bond. This electron rich

Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting

Jacobsen reported that chiral manganese complexes had the ability to catalyze the asymmetric epoxidation of unfunctionalized alkenes‚ providing enantiomeric excesses that regularly reaching 90% and sometimes exceeding 98% . The chiral manganese complex Jacobsen utilized was [(R‚R)-N‚N’-Bis(3‚5-di-tert-butylsalicylidene)-1‚2- cyclohexanediaminato-(2-)]-manganese (III) chloride

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex
