WebJan 28, 2024 · In this case, conferring Hückel 4n+2 aromaticity. For furan with two lone pairs on the oxygen atom, if we count electrons from the carbon atoms, we have 4 (one per carbon). So adding two electrons from one of the lone pairs will give 6 = 4 (1)+2, so Hückel rule is applicable and furan is aromatic. Exercise 15.3.1.
Craig rule of aromaticity
Did you know?
WebIn 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4n+2 π electrons, it is considered aromatic. This rule would come to be known as Hückel's Rule. WebCraig's rule is important to understand the Aromaticity in polycyclic non-benzenoid molecules. Continue on app (Hindi) Aromatic Compounds and Aromaticity : IIT JEE. 20 …
