Objectives<\/h3>\r\n
\r\n
\r\n
\r\n\r\nAfter completing this section, you should be able to\r\n
    \r\n \t
  1. explain why cis alkenes are generally less stable than their trans isomers.<\/li>\r\n \t
  2. explain that catalytic reduction of a cis alkene produces the same alkane as the catalytic reduction of the trans isomer.<\/li>\r\n \t
  3. explain how heats of hydrogenation (\u0394H<\/em>\u00b0hydrog<\/sub>) can be used to show that cis alkenes are less stable than their trans isomers, and discuss, briefly, the limitations of this approach.<\/li>\r\n \t
  4. arrange a series of alkenes in order of increasing or decreasing stability.<\/li>\r\n \t
  5. describe, briefly, two of the hypotheses proposed to explain why alkene stability increases with increased substitution.\r\n
    Note:<\/strong> This problem is a typical example of those instances in science where there is probably no single \u201ccorrect\u201d explanation for an observed phenomenon.<\/blockquote>\r\n<\/li>\r\n<\/ol>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n
