Question

Draw the molecule by placing atoms on the grid and connecting them with bonds. Do not identify the charge on each of these species. Include all lone pairs of electrons.

H3COCH3

Draw the ion by placing atoms on the grid and connecting them with bonds. Do not identify the charge on each of these species. Include all lone pairs of electrons.

NO2 -

Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons and nonbonding electrons. Show the formal charges of all atoms in the correct structure.

PO4 -3

CN - (I tried doing this one, but I was incorrect)

SO3 -2

ClO2 -

Answer 1

We can't draw diagrams on this forum because of spacing problems; your best bet is to google each; e.g., lewis dot structure PO4^3- etc.
I can draw CN^-. It is
:C:::N: and it has a -1 charge on it.
