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.
Draw the best LS (with lowest formal charges) for BeAt2 on a sheet of paper (NOT TO BE TURNED IN) and answer the following:
(NOTE: Use the cardinal numbers 0, 1, 2, 3, and so on for any quantity required)
a) give the number of lone electron pairs on Be atom. pairs
b) give the number of lone electron pairs on each At atom. pairs
c) what types of bonds are attached to Be? (choose correct letter from A – D):
|
A. two double bonds
|
C. two single bonds
|
|
B. a single & double bond
|
D. a double & triple bond
|
d) Fill in the table below for BeAt2. For prediction of the actual bond angle, if the angle is ideal give the numerical value; if the angle is different from ideal use > (greater than) or < (less than) with the numerical value of the ideal bond angle (for e.g., < 1800).
{ NOTE:
i) The correct spelling of the names matters. Be sure to check your spelling.
ii) For the hybridization, place the superscript numbers on the same level as the letters. For example, “sp3” should be written as sp3 & “sp3d2” as sp3d2, and so on.
iii) For the bond angle,
a) put one space between the inequality sign and the number & do NOT put any units. For example, “less than 109.5o” should be written as “< 109.5”.
b) if there is more than one bond angle, give the smallest one in your answer. So, if bond angles are 90, 120 & 180o, use only 90o in your prediction.
iv) For the polarity, write the full words: “polar” or “nonpolar”.}
