Marta Gebregziabher Discussion and conclusion 10: Preparation of Fluorenol 1. A reduction reaction is a reaction that describes the decrease in oxidation number of a molecule, or the atom gaining electrons. In this experiment, we prepare Fluorenol by reducing 9-fluorenone. One of the two ways to reduce this compound is by using a catalyst but the big problem with this method is the H2 gas that is generated. Another way to reduce 9-fluorenone is by using a reducing agent. A reducing agent is helpful in the reaction because it donates a hydrogen anion (H: -). One reducing agent is tetrahydridoborate, also known as, sodium borohydride. This agent reduces ketone’s and aldehyde’s into alcohols. It is soluble in water and methanol, but it vigorously reacts with water. Another good reducing agent is Lithium aluminum hydride, LAH. This reducing reagent reduced amides, esters and carboxylic acids into primary alcohol and is very reactive with water. H2 is released when it reacts with water. This reducing reagent is much stronger and more preferred than
