1. For the molecule shown below: H :O: || C-C- H -N-H H H a) Draw any valid resonance contributors (meaning you are not breaking the octet rule) b) Rank the contributors (Give the ranking of 1 to major and the higher the number, the less relevant the contributor) c) In all contributors you have drawn, label the hybridization of each atom in the structure d) There will be some atoms that have one hybridization in one contributor, but a different hybridization in a different contributor (e.g. the carbon may be sp³ in one contributor, but sp² in another). Identify the atoms where the hybridization changes in different contributors. e) What is the key requirement for a pair of atoms to share electrons in a + bond? f) An atom in within a molecule only has one hybridization. There are some atoms where it appears the hybridization changes between different contributors, but the atom really only has one hybridization. Which of the two possible hybridizations for these atoms is correct? Explain your selection. In your explanation, you will want to consider that the electron sharing is best described with a resonance hybrid and that if a pair of electrons is shared between atoms in one contributor, electron density is continuously being shared between those atoms - and therefore the atoms must continuously meet the requirements to share electrons (part e).

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.

H
a) Draw any valid resonance contributors (meaning you are not breaking the octet rule)
b) Rank the contributors (Give the ranking of 1 to major and the higher the number, the
less relevant the contributor)
c) In all contributors you have drawn, label the hybridization of each atom in the structure
d) There will be some atoms that have one hybridization in one contributor, but a different
hybridization in a different contributor (e.g. the carbon may be sp³ in one contributor,
but sp² in another). Identify the atoms where the hybridization changes in different
contributors.
e) What is the key requirement for a pair of atoms to share electrons in a bond?
f) An atom in within a molecule only has one hybridization. There are some atoms where
it appears the hybridization changes between different contributors, but the atom really
only has one hybridization. Which of the two possible hybridizations for these atoms is
correct? Explain your selection. In your explanation, you will want to consider that the
electron sharing is best described with a resonance hybrid and that if a pair of electrons
is shared between atoms in one contributor, electron density is continuously being
shared between those atoms - and therefore the atoms must continuously meet the
requirements to share electrons (part e).
