WebThe even–odd rule is an algorithm implemented in vector-based graphic software, like the PostScript language and Scalable Vector Graphics (SVG), which determines how a graphical shape with more than one closed outline will be filled. Unlike the nonzero-rule algorithm, this algorithm will alternatively color and leave uncolored shapes defined by nested closed … WebVideo transcript. We have seen that a compound or ion is aromatic if it contains a ring of continuously overlapping p orbitals, and also if it has 4n plus 2 pi electrons in the ring, where n is an integer. So for example, n could be 0, or 1, or 2, or so on. We can use these criteria to analyze the cyclopropenyl cations.
