WebResonance structures with the lowest amount of energy are known to be the most stable. This is significant because the greater the stability of a singular structure, the more it will contribute to the resonance hybrid. The most stable structures are known as … WebThese two drawings are an example of what is referred to in organic chemistry as resonance contributors: two or more different Lewis structures depicting the same molecule or ion that, when considered together, do a better job of approximating delocalized pi-bonding than any single structure.

WebDec 29, 2014 · A major resonance contributor is one that has the lowest energy. We can often write more than one Lewis structure for a molecule, differing only in the positions of the electrons. Each individual structure is called a resonance contributor. The most stable structures contribute most to the resonance hybrid. They are called the major … WebStructure (i) has 11 bonds and makes a more significant contribution than the other two structures, which have only 10 bonds. Since the contributing structures are not equivalent, the resonance energy is small. [Pg.149] No. The product consists of an equal number of HjC = CH CH2Br and CHj = CHCHjBr molecules.
