Concept explainers
(a)
Interpretation:
For the given ion, all the resonance structures are to be drawn.
Concept introduction:
If a molecule or ion has one of the following features, another resonance structure will exist:
- A lone pair on an atom adjacent to a multiple bond
- An atom with incomplete octet next to a multiple bond or next to an atom with one or more lone pairs.
- Alternating double/triple and single bonds.
The movement of an electron pair is shown with a curved arrow, starting at the pair and ending on the atom or region where it moves. The movement must be from a relatively electron rich atom or region to a relatively electron deficient atom or region.

For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
