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 -

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.

H3COCH3:

To draw the molecule H3COCH3, follow these steps:

1. Start by placing a carbon atom in the center of the grid. Carbon has four valence electrons.

C

2. Next, place three hydrogen atoms around the carbon atom, making sure each hydrogen atom forms a single bond with the carbon. Each hydrogen atom has one valence electron.

H-C-H-H

3. Attach an oxygen atom to the carbon atom, forming a single bond between them. Oxygen has six valence electrons.

H-C-O-H-H

4. Finally, attach a methyl group (CH3) to the oxygen atom. This methyl group consists of one carbon atom bonded to three hydrogen atoms.

H-C-O-CH3

To draw the molecule and ion structures, you will need to follow a few steps:

First, determine the central atom in each structure. The central atom is typically the least electronegative element, or the one with the highest valence electrons.

1. H3COCH3:
The central atom in this molecule is carbon (C). Carbon will be placed in the center of the grid.
- Place three hydrogen atoms (H) around the carbon atom, ensuring each hydrogen has a single bond with the carbon atom.
- Attach an oxygen atom (O) to the carbon atom with a single bond.
- Attach another carbon atom (C) to the oxygen atom with a double bond.
- Finally, attach three hydrogen atoms (H) to the second carbon atom.

The structure should look like this:
```
H H
| |
H-C-O-C-H
| |
H H
```

2. NO2 -
The central atom in this ion is nitrogen (N). Nitrogen will be placed in the center of the grid.
- Attach an oxygen atom (O) to the nitrogen atom with a double bond.
- Attach another oxygen atom (O) to the nitrogen atom with a single bond.
- Each oxygen atom should have one lone pair of electrons.

The structure should look like this:
```
O
||
N - O
```

3. PO4 -3
The central atom in this ion is phosphorus (P). Phosphorus will be placed in the center of the grid.
- Attach four oxygen atoms (O) to the phosphorus atom with single bonds.
- Each oxygen atom should have one lone pair of electrons.
- In the final structure, the phosphorus atom should have a formal charge of -3, while each oxygen atom should have a formal charge of -1.

The structure should look like this:
```
O
|||
O = P = O - O
|
O
```

4. CN -
The central atom in this ion is carbon (C). Carbon will be placed in the center of the grid.
- Attach a nitrogen atom (N) to the carbon atom with a triple bond.
- The nitrogen atom should have one lone pair of electrons.

The structure should look like this:
```
N
||
C
```

5. SO3 -2
The central atom in this ion is sulfur (S). Sulfur will be placed in the center of the grid.
- Attach three oxygen atoms (O) to the sulfur atom with double bonds.
- Each oxygen atom should have two lone pairs of electrons.
- In the final structure, the sulfur atom should have a formal charge of -2.

The structure should look like this:
```
O
||
O = S = O
||
O
```

6. ClO2 -
The central atom in this ion is chlorine (Cl). Chlorine will be placed in the center of the grid.
- Attach an oxygen atom (O) to the chlorine atom with a double bond.
- Attach another oxygen atom (O) to the chlorine atom with a single bond.
- Each oxygen atom should have two lone pairs of electrons.
- In the final structure, the chlorine atom should have a formal charge of -1.

The structure should look like this:
```
O
||
O = Cl = O
```

Remember that these are just representations of the molecular structures, and the actual bond angles may deviate slightly based on the specific properties of the atoms involved.
