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.
True or False
1. Liebermann-Burchard Test -Color change is due to increasing conjugation of the double bond in adjacent fused ring
2. Liebermann-Burchard Test -Acetic anhydride reacts with the aliphatic hydrocarbon.
3. Salkowski Test - The chloroform layer turns red.
4. Salkowski Test - Involves the reagents chloroform, sulfuric acid and acetic anhydride
5. Liebermann-Burchard Test -Reaction involved is esterification.
6. Keller-Killiani Test - Involves color reaction of the sugar 2-deoxyhexose
7. Salkowski Test - The upper layer turns yellow with green fluorescence
8. Liebermann-Burchard Test -Must observe the color right away because it happens in a very short period of time.
9. Liebermann-Burchard Test - Chloroform was added to react with sulfuric acid.
10. Keller-Killiani Test - Color change results to reddish brown that turns into violet or purple
