Q.2 (iii) Write the total number of chiral carbon atoms present in glucose.
Best answer
Answer: 4
In the open-chain structure of glucose, CHO–(CHOH)4–CH2OH, carbon atoms C-2, C-3, C-4 and C-5 each carry four different groups, so there are 4 chiral carbon atoms (giving 24 = 16 stereoisomers). (In the cyclic pyranose form C-1 also becomes chiral, giving 5.)
