The following is a skeleton of a molecular anion having the overall formula C7H6NO–. The H atoms are not shown. Starting with the structure drawn below, complete the Lewis structure by adding all H atoms, valence electrons, and π bonds. This structure will have a –1 formal charge on the oxygen.
PROVISIONAL LEWIS STRUCTURES T01/S02
For each provisional structure, enter the central atom formal charge (if not zero, enter the sign before the value) and, separating by comma without any space, indicate (Y or N) if it is the correct
Lewis structure. For example, your answer could be "-2,Y".

In the following Lewis structure of [SiF6]²;, every atom, bond and lone pair is positioned. To complete the structure, drag the formal
charge tags to the appropriate atom(s). Each marker may be used more than once, or not at all. If an atom has a formal charge of zero,
do not drag a tag to it.
When you drag the marker in, place the little crosshairs in the upper left corner of the marker directly over the atom(s) in
question (not above them).
