(a)
Interpretation:
The possible resonance structures for the following structure have to be determined. Also, the resonance structure that is the most important has to be determined.
Concept introduction:
The steps to draw the Lewis structure of the molecule are as follows:
Step 1: Find the central atom and place the other atoms around it. The atom in a compound that has the lowest group number or lowest electronegativity considered as the central atom.
Step 2: Estimate the total number of valence electrons.
Step 3: Connect the other atoms around the central atoms to the central atom with a single bond and lower the value of valence electrons by 2 of every single bond.
Step 4: Allocate the remaining electrons in pairs so that each atom can get 8 electrons.
The formula to calculate formal charge of the atom is as follows:
Formal charge=(number ofvalenceelectrons)−((number of lone pairs of electrons )+(12) (number of shared electrons)) (1)
Some molecules and ions do not have one unique Lewis structure. The Lewis structures that differ only in the placement of multiple bonds are called resonance structures.
Resonance structures are defined as a set of two or more Lewis structures that collectively describe the electronic bonding. The actual bonding is an average of the bonding in the resonance structures. Also, not all resonance structures contribute equally in every case. Resonance structures that have high formal charges or that place charges of the same sign on adjacent atoms do not contribute to the bonding.
(b)
Interpretation:
The possible resonance structures for the following skeleton structure have to be determined. Also, the most important resonance structure has to be identified.
