A curved arrow mechanism for a Bronsted acid-base reaction is shown below. Choose the best explanation for this proposed curved arrow mechanism. :0: :O-H 个回 A) The arrow points at the proton that is electron deficient. The hydroxide ion is electron deficient due to the difference in the electronegativity between the oxygen and the hydrogen atoms. The arrow indicates that the electron rich hydrogen of the carboxylic acid (RC(=O)-O-H) moves to the oxygen of the hydroxide ion to form water. B) The arrow points at the proton that is electron rich. The hydroxide ion is electron deficient due to the difference in the electronegativity between the oxygen and the hydrogen atoms. The arrow indicates that the electron rich hydrogen of the carboxylic acid (RC(=O)-O-H) moves to the oxygen of the hydroxide ion to form water. C) The arrow points at the proton that is electron deficient. This proton is bonded to an electronegative oxygen creating a dipole that leaves the hydrogen with a low electron density. The electrons follow the arrow fro+ the base (HO) to the proton showing the formation of a new bond. The second arrow
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.
