    Megan Entwistle‚ Maria Amos‚ and Paul Golubic CHEM 0330 Organic Lab 1 Sodium Borohydride Reduction: Diphenylmethanol from Benzophenone 11/16/11 Introduction Redox (shorthand for REDuction-OXidation) reactions are chemical reactions in which the oxidation state (or oxidation number) of atoms has changed. Oxidation can be observed through the loss of electrons or an increase in oxidation state by an atom‚ ion or molecule. Reduction describes the gain of electrons or decrease in oxidation state

    EXPERIMENT I Photoreduction of Benzophenone Introduction The study of chemical reactions‚ isomerizations and physical behavior that may occur under the influence of visible and/or ultraviolet light is called Photochemistry. The fundamental principles for understanding photochemical transformations are that light must be absorbed by a compound in order for a photochemical reaction to take place‚ and that for each photon of light absorbed by a chemical system only one molecule is activated for

    Abstract In this experiment it is aimed to synthesize benzopinacol through photochemical reaction of benzophenone and‚ benzopinacolone via acid-catalyzed rearrangement of benzopinacol. In this experiment‚ mixture of benzophenone‚ isopropyl alcohol and a drop of glacial acetic acid was exposed to sunlight which in turn‚ undergone photochemical reaction. In this reaction‚ molecules of benzophenone was brought to n((* triplet state where it possibly abstracted hydrogen from isopropyl alcohol and through
