  • Learning Objectives:

    After reading the chapter and completing the exercises and homework, a student can be able to:

    • describe the electronic structure of alkenes using Molecular Orbital (MO) Theory and Orbital Hybridization - refer to section 8.1
    • memorize the common names for vinylic and allylic groups including isoprene and styrene refer to section 8.2
    • predict the relative physical properties of alkenes - refer to section 8.2
    • recognize and classify the stereochemistry of alkenes using the cis/trans and E/Z systems - refer to section 8.3
    • calculate the Degrees of Unsaturation (DU) and apply it to alkene structure - refer to section 8.4
    • give the IUPAC names for alkenes given their structure & vice versa including E/Z isomers - refer to section 8.5 and chapter 3
    • use heats of hydrogenation to compare the stabilities of alkenes - refer to section 8.6
    • interpret and draw reaction energy diagrams for dehydrohalogenation of R-X’s and alcohol dehydration reactions - refer to sections 8.7 and 8.8 respectively and chapter 7
    • propose mechanisms for a dehydrohalogenation or dehydration reactions - refer to sections 8.7 and 8.8 respectively and chapter 7
    • predict the products and specify the reagents for alkene synthesis from dehydrohalogenation of R-X’s and alcohol dehydration reactions - refer to sections 8.7 and 8.8 respectively
    • predict and explain the stereochemistry of E2 eliminations to form alkenes, especially from cyclohexanes - refer to sections 8.7 and 8.8 and chapter 7
    • discuss the uses and sources of alkenes including catalytic cracking - refer to section 8.9
