    | |Structure and Preparation of Alkenes. | |Elimination Reactions | Summary Alkenes contain the C=C functional group which can be prepared by 1‚2-elimination reactions such as: • dehydration of alcohols (- H2O) or • dehydrohalogenation of alkyl halides (- HX). Zaitsev’s rule indicates that the preferred product is the more highly substituted‚ and therefore more stable alkene. But the rule is not always obeyed

    Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including
