Taxol is a cancer chemotherapy drug isolated from the bark of the pacific yew tree, and name five (4) major functional groups. Bonus) 1-Dccanol is an important reagent used in the synthesis of surfactants, lubricants and plasticizers. On a lab scale 1-decanol can be produced from 1 decene via a hydroboration-oxidation reaction. Assume that each mole of alkene is converted into 1 mole of alcohol. How much alkene starting material will you to produce 1 Kg of alcohol Molar mass...

2. I he compound below known as salicin is an old natural painkiller (from tree bark). In the presence of water and acid, salicin will be metabolized into a cyclic hemiacetal and the actual drug. Please provide the products of this reaction and a detailed mechanism, using curved arrows to indicate the movement of electrons. Hint: The ether oxygen on the benzene ring is somewhat more basic than the other ether oxygen. ?? ?? cat. H+ and H2O ?? ??...

ОН 3. Glucuronic acid is an oxidized derivative of glucose found in animal secretions such as saliva. Biological conversaion of glucuronic acid into its isomer, fructuronic acid, is catalyzed by an enzyme called uronic acid isomerase O OH OH o= H2O, H* OH uronic acid isomerase HO O O H OH glucuronic acid fructuronic acid a. Provide a complete curved-arrow mechanism for this transformation. You may assume that the enzyme active site will supply all necessary equivalents of water and...

TRUE OR FALSE 1. Complex applicant selection systems are most often found in larger organizations. 2. In structurally complex organizations with many job titles but very few occupants, the number of years needed to pay back the money invested in a complex selection system almost always justifies its initial expense 3. One of the most significant environmental influences on selection is the size, composition, and availability of local labor markets. 4. When unemployment rates are low, it may be difficult...

EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
