Nabiha Baseer 3/28/11 Experiment 16: Some Chemistry of Alpha-Pinene Oxide Purpose: The purpose of this experiment is to study the physical characteristics of reactions with alpha- pinene oxide. Discussion: The mass spectroscopy shows a molecular ion of 170 m/z, so 18 grams of a substance must have been added since the m/z for alpha-pinene oxide is 152 m/z. This substance is most likely water because this reaction was carried out in a solvent mixture and there is water in the acid solution. Water will attack all the carbocations. Therefore the mass spectroscopy indicates water addition. This also implies that the product is similar to the starting material. My mechanism analysis proposes that the epoxide will open to form an alcohol and the carbocation that is created might be quenched by an elimination reaction (C=C double bond formation) and/or another water addition. The two TLC plates I developed were good indicators of a decomposition reaction taking place. In the first TLC plate, no spots were visible in UV but several spots showed up iodine. This
