Question 1 [1.3 pts] ich one of the following statements about asymmetric center Win Figure 1 is correct? O The configuration of asymmetric center Wis R O The configuration of asymmetric center W is S Figure 1 OH Question 2 [1.3 pts] ich one of the following statements about asymmetric center X in Figure 1 is correct? O The configuration of asymmetric center X is R O The configuration of asymmetric center X is S Question 3 [1.6 pts] What sugar is the C-5 epimer of D-glucose? Question 4 [1.6 pts] What sugar is the C-3 epimer of D-fructose? Question 5 1.6 pts] What is the identify of compound 1? Question 6 1.6 pts] What is the identify of compound 2?Explanation / Answer
Q1) The configuration at W is R .
The least priority group on horizaontal and 1->2 --> 3 is going anticlockwise, thus R
Q2)The configuration at X is R
The least priority is on vertical line and 1--> 2---> 3 is going clockwise, thus R [CH2S gets more priority over -COOH]
Q3) Epimers are the diasteromers in which the configuration at only one chiral carbon is reversed.
Thus C-5 epimer of glucose should be classified as L - compound and L-idose is the C-5 epimer of D-glucose.
Q4) C-3 epimer of D-fructose is D-psicose .
Q5) structure 1 is beta -D- fructopyranose
