For the following Structure, a) draw in any missing lone pairs; b) identify and list the resonance patterns (i.e. allylic cation) present. If one pattern shows up more than once, list it multiple times c) draw curved arrows on the initial structure to produce a resonance structure, including formal charge. (hint - use a minimum of curved arrows for each resonance structure). Repeat on the second structure to generate a third structure. Rank the resonance structures in order of decreasing importance: 1 is most important, 2 is second most important, etc...

Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlled by the electron repulsion or attraction producing in another portion of the molecule.
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the molecule's entire electronic structure. One Lewis diagram cannot explain the bonding (lone pair, double bond, octet) elaborately. A hybrid describes a combination of possible resonance structures that represents the entire delocalization of electrons within the molecule.
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular structures of various compounds can help in predicting equilibrium.
