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.
Hello! I'm a tad confused about this question. What would be the correct answer?
The salt behavior as well as its solution pH is wholly dependent on its constituents acid-base pair. The species (acid/base) which is stronger in nature will decide the solution's pH and in turn affect its pH value.
In option (C), the compound CH3NH3CN is formed by the combination of weak base (methylamine CH3NH2) and weak acid (HCN) as shown below.
These weak acids-base dissociates feebly in solutions. The pH of solution as well as acidic/basic nature of CH3NH3CN will depend on the concentration of acid and base.
Hence, their Ka or Kb value is required.
Thus, it is the correct option.
