Molecules with this property include the carboxylate ion, which has two bonds of order three halves, and they are shown as a hybrid of Lewis structures.
Examples of this property include the norbornyl cation and diborane's three-center two-electron bonds, and this phenomenon's greater strength as stability decreases makes it more active in excited states, allowing dyes to function. This property's effect on the electron donating or withdrawing character of a group is called the mesomeric effect, and its stabilization energy is named for Dewar. Molecules with this property include the carboxylate ion, which has two bonds of order three halves, and they are shown as a hybrid of Lewis structures. For 10 points, name this phenomenon, an extreme form of which is aromaticity, in which electrons delocalize across multiple atoms.
Examples of this property include the norbornyl cation and diborane's three-center two-electron bonds, and this phenomenon's greater strength as stability decreases makes it more active in excited states, allowing dyes to function.
