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.
I hypothesize that my unknown is benzene based on my density but how do i explain ?
The qualitative estimation of the hypothesis of the compound being benzene can be done by chemically testing.
The compound can also be tested by taking a small amount of the compound towards the flame of the bunsen burner. If the colour of the flame changes to yellow with a sooty flame, it indicates the presence of the aromatic compounds (e.g. Benzene)
Benzene also readily reacts with the bromine solution to give the test for unsaturation. The colour of the bromine water decolourizes in this reaction.
