How extensive is the conjugated system in the beta-lactam of the penicillin shown below ?
Options:
Answer:
B
Solution:
In the beta-lactam ring only N, C=O (3 atoms) are conjugated. The side-chain amide N-C=O is a separate 3-atom system, and the COOH is a third isolated unit (they are separated by sp³ carbons). The ring system is not extended.
