Concept explainers
Interpretation:
For each of the given compounds, all the possible resonance structures are to be written including the appropriate formal charges.
Concept introduction:
Resonating structures are structures that have more than one equivalent Lewis structure for the same molecule or ion.
According to the convention, these structures are connected by double-headed arrows (
Movement of electrons (whether bonding or lone pair) is indicated by curved arrows.
The rules for writing the resonance structures are:
Resonance structures have existence in papers only, they are not real structures.
While writing the resonance structures, movement of either double bonded electrons or lone pair of electrons are shown.
All structures should be correct Lewis structures.
The energy of any contributing structure is higher than the energy of the resonance hybrid.
For equivalent resonating structures, the resonance stabilization is large.

- In the Lewis structure for chloromethane, the chlorine atom is sharing _____ electron pair and “owns” _____ of those electrons. Also, the chlorine atom possesses two electrons from each of _____ unshared pairs. The total number of electrons that belong to chlorine is 7 . Chlorine is a Group ____ element. The formal charge on chlorine in chloromethane is ____.arrow_forwardEthanol, , is a compound in which the formal charge on all the atoms is zero. Under certain conditions the bond can be broken so that both electrons remain with the oxygen atom. The products are In this structure the oxygen owns one electron from shared pair and two electrons from each of unshared pairs. The total number of electrons belonging to oxygen is Oxygen is a Group element. The formal charge on the oxygen atom is . The correct Lewis structure for the ethoxide ion is Note that the other fragment, the proton, leaves with a formal charge of +1.arrow_forwardThe carbon atom owns one electron from each of shared pairs and two electrons from unshared pair. The number of electrons that belong to carbon is . Carbon is a Group element. Since the carbon atom has one more electron than it would in the neutral, unbonded state, it has a formal charge of –1 . The Lewis structure for the methyl anion is The lithium fragment must have a formal charge ofarrow_forward
- Keeping the same atomic connections and moving only electrons, write a more stable Lewis structure for each of the following. Be sure to specify formal charges, if any, in the new structure. (g) (h) (i)arrow_forwardProvide three additional resonance structures (not including the original structure) for the molecule shown below. You must show all lone pair electrons and all formal charges.arrow_forwardplease explain alsoarrow_forward
- Choose the INCORRECT statement. In a Lewis structure, the number of valence electrons shown is one more for each negative charge. The central atom is typically the atom with the highest electronegativity. Formal charges are apparent charges associated with atoms in a Lewis structure. Resonance is when more than one plausible structure can be written but the "correct" structure cannot be written.arrow_forwardTwo major resonance structures are possible for the anion shown. One resonance form is given, but it is incomplete. Complete the given structure by adding nonbonding electrons and formal charges. Draw the remaining structure, including nonbonding electrons and formal charges. Omit curved arrows. Structure A: complete the structure by adding nonbonding electrons and formal charges.
