How many separate conjugated systems are there in podophyllotoxin ?
Options:
Answer:
C
Solution:
The trimethoxyphenyl ring (with its three OCH₃ oxygens) is one conjugated system. The methylenedioxy-benzene ring (with its two O atoms) is a second. The lactone C=O with the ring O lone pair is the third. They are separated by sp³ carbons, so there are 3 separate systems.
