Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After

1)Why does Coelho open with the modified myth of Narcissus? How does the new version differ from the original one? How does it change the myth’s meaning? What might the author be suggesting about how we perceive ourselves and the world? Paulo Coelho began with the tale of Narcissus to show the reader that when you are so caught up in your own life you do not realize the greater things like nature and friends. It differs because it leaves out how the lake was also too caught up in its own beauty

Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent
