Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Asymmetric (chiral) carbons are carbon atoms bonded to four different groups.
Step 2: Meaning
The tetracycline skeleton is complex, consisting of four fused rings with multiple functional groups.
Step 3: Analysis
Oxytetracycline has chiral centers at positions C-4, C-4a, C-5, C-5a, C-6, and C-12a.
Step 4: Conclusion
There are a total of 6 asymmetric carbon atoms in the oxytetracycline molecule. Final Answer: (C)
