1) The major component of orange oil is limonene which has a specific rotation of +115.5°. Compare this value with the specific rotation you calculated from your own sample. Is your sample pure? Describe a method you might use to determine the composition of your mixture. My specific rotation was +17.425

2) Many organic reactions result in mixtures of enantiomers in equal amounts, a racemic mixture, which results in zero observable rotation. Chemists have developed selective reactions that result in more of one enantiomer than the other (enantiomer excess). If a mixture of R and S enantiomers has an observed rotation is +25° and the S enantiomer has a +45° rotation, calculate the % enantiometric excess and composition of the mixture.
