Answer 2

3. Furan is a non-benzenoid molecule.

Explanation:

• The benzenoid structures are those aromatic compounds which do not have a benzene ring in their structure.
• They have a conjugated system and they are planar in structure.
• The furan molecule is a five membered ring with oxygen atom in its molecule. Its molcular formula is C₄H₄O.
• It is a non-benzenoid molecule as it does not contain a benzene ring.
• Whereas naphthalene, and toluene contains benzene ring in their structure.
• Therefore, option (3) furan is correct.
