    SN1 Reactions For SN1 reactions it’s important to have a good leaving group because this reaction occurs in two steps. Because alcohol is such a poor leaving group it needs to be helped by silver nitrate to help promote the ionization of the alkyl halide. This helps form the products of the SN1 reaction. 2-chlorobutane This reaction didn’t occur because the carbocation isn’t stable enough for an SN1 reaction. 2-bromobutane This reaction occurred in 32 seconds. This reaction occurred quickly

    Organic Lab 2 February 14‚ 2009 Experiment 4: Borohydride Reduction of 2-Methylcyclohexanone Introduction: When learning about reduction reactions‚ we know that the addition of nucleophilic hydride anion (H-) to the carbonyl group will in turn result in the reduction of aldehydes to primary alcohols. Borohydride‚ and Lithuim aluminum hydride are commonly used as reducing agents. We can note that both of these reagents have a (H-) anion‚ hence it will be a powerful base and also take the

    February 2012 Esterification of Isopentyl Alcohol to Isopentyl Acetate Procedure The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This mixture was acid catalyzed by the addition on two drops of
