Question

5. (5.0 points) In which of the following groups can the carbon atom be a chiral center? CH2 C. e. The carbon atoms cannot be a chiral center in any of these groups. Answer:- 6. (7.5 points) A white solid known to be enatiomerically pure is dissolved in water. This solution produced an observed optical rotation of +45.6. The solution was allowed to stand and the optical rotation was measured repeatedly producing the data shown in the table. Time Observec (min) Rotation () +39.9 +5.6 10 20 30 40 40 -23.4 -23.4 Explain the pattern of observed rotation. Answer:

Explanation / Answer

5) To be chiral the carbon atom must be bonded directly to four different atoms or groups. Thus, in this light, none of the carbon given are chiral.
