7. Draw a Fisher structure for glucose and label the chiral carbons. 8. How does an oligosaccharide differ from a polysaccharide? 9. In the test using Fehling's solution-What element is responsible for the color change? What is the element or compound responsible for each coter listing the color of each?
1. Construct a model of the 2,3-dibromopentane isomer and label the chiral centers as R or S. Then make a model of its mirror image and draw it below, again labeling the chiral centers as R or S. a. Convert both models to their most stable conformation and draw their Newman projections looking down the center bond. b. On one model interchange the H and Br on one of the chiral centers. How is this molecule related to the other...
9. Using Fisher projections, draw all of the possible stereoisomers for 3,4- difluorohexane. For each stereoisomer, determine the absolute configuration for each stereogenic carbon. Then, determine the relationship between each set of stereoisomers. (25 points)
1. (12pts) Determine if each compound below is chiral or achiral and circle the label that describes each one. Without using the (R)/(S) system, show work to justify each answer by drawing the mirror image and clearly illustrate whether or not the mirror images are superimposable. - Br НСІ - - - (a) Hvac= - (b) AY (C) - " Нcc - CH3 - - Br - - - Chiral or Achiral Chiral or Achiral Chiral or Achiral Chiral or...
