Consider the following reaction: O: 1. NaBH H3C CНз 2. D20 CH3 Complete the electron-pushing mechanism for the reaction by drawing the necessary organic structures and curved arrows for each step. Make sure to include all nonbonding electron pairs. Step 1: treatment with NaBH4 Add curved arrows for the first step. Treat Na as a spectator ion. Na -В- НзС. Cнз H CHз Step 2: treatment with D2O Add curved arrows for the second step Do not show Na* counter ion :ö |НзС- CH3 СHз Final products Draw the products of the last step (hint: one organic and one inorganic species), including all nonbonding electron pairs. Do not show Na* counter ion
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.
If my first arrows are correct, then what would the second arrows look like?
