Which is more stable, furan or buta-1,3-dien-1-ol (, open chain) ?
Options:
Answer:
C
Solution:
Furan is cyclic and planar, and its ring has 6 π electrons (2 and one O lone pair, 4n+2 with n = 1), so it is aromatic. The open-chain analogue has no ring delocalisation of this kind, so furan is more stable.
