Homework Answers
Answer will be option (D), that is structure III, IV.
Explanation: If we draw frost circle diagram of given structure that is Pyrole, which is 6πe system. So structure III, IV represent HOMO molecular orbitals.
Structure I is not representing HOMO structure, as node has passed but lobe sign has not changed.
Structure II is not also HOMO.
So, option (D) is correct answer as it includes structure III, IV.
