WebAromatic Compounds: In order to consider a compound to be aromatic, it has to satisfy four criteria. The compound (1) should be planar, (2) should be completely conjugated, (3) should be cyclic, and (4) should satisfy Huckel's rule. If at least one of these is not satisfied, then the compound is not aromatic. Answer and Explanation: 1 WebHuckel’s Rule: 4n+2 = Number of Resonating Electrons. Resonating electrons include both pi electrons and lone pairs. When solving for ‘n’, n must equal to a whole number. If we …

WebThe Criteria for Aromaticity. In 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 … WebYou just want the number of pi electrons you have to follow the rule. For example, if you had 7 pi electrons and plugged that into Huckel's rule you would get n = 1.25. Since 1.25 isn't an integer the compound isn't aromatic. If n is a positive integer then that satisfies one requirement of being aromatic.
