WebIt is cyclic and planar. It has 6 π electrons (where n = 1). Now let’s look at some other conjugated cyclic compounds. Cyclobutadiene This molecule is cyclic, apparently fully conjugated, and planar. How many π electrons does it have? Answer: 4 (a double bond is made of 2 π electrons. There are two double bonds, therefore, 4 π electrons) Webiii) For the π-cloud to be formed, each p-orbital must be able to overlap with the p − orbitals on either side of it. Therefore, the molecule must be planar. b) The π-cloud must contain an odd number of pair of π-electrons , (4 n + 2) π-electrons, where n is an integer. The stability order of the three compounds is: WebThis question is synonymous to asking how many π electrons there are. Double bonds and the lone pairs on the nitrogen account for the π electrons.
