A ketone is a compound with the structure RC(=O)R’, where R and R’ can be a variety of atoms and groups of atoms. It features a carbonyl group (C=O) bonded to two carbon atoms and the oxygen center is more electronegativity than that for carbonyl carbon. Thus, ketones are nucleophilic at oxygen and electrophilic at carbon. Ketones are converted to alcohols by reduction with sodium borohydride followed by hydrolysis in an aqueous acidic workup. In this reaction, a hydride anion from the borohydride is transferred to the electropositive carbon of the carbonyl group. Sodium borohydride, NaBH4, are widely used in reducing carbonyl groups. The reduced reactivity of borohydride allows it to be used even in alcohol and water solvents. Sodium borohydride were used in this experiment because it is easier to be handled.
