I need help answering these 3 chemistry post lab questions. Please type your answers in a word document. 10. Compare the calculated optical purity of the experimental orange oil and standard orange oil. What in general can contribute to the discrepancy? What could possibly contribute to the discrepancy in your case? (3 pts).11. (R)-(+)-limonene has a boiling point of 176 °C. What made it possible to steam distill it below 100 °C? Would it be possible to steam distill a mixture of ethylene glycol and water? Explain. (Ethylene glycol has a boiling point of 196 °C at 1 atm, and it is soluble in water.) (3 pts).12. Explain the difference between the specific rotation of standard orange oil and specific rotation of (R)-(+)-limonene reported in literature. (3 pts)
