add formal charge where appropriate. can you also help me with the calculations? Thanks

 

 

The image contains several molecular structures represented in a 2D format. Here's a detailed transcription and explanation:

1. **Phosphine with Hydrocarbons**:
   - Structure: A phosphorus atom (P) is centrally bonded to three carbon atoms (C). 
   - Each carbon has three hydrogen atoms (H) attached.
   - The structure can be represented as:
     ```
       H  H  H
       |  |  |
     H-C-P-C-H
          |
       H-C-H
     ```

2. **Isocyanide**:
   - Structure: A carbon (C) is triple-bonded to nitrogen (N), which has two lone pairs of electrons. 
   - The carbon is singly bonded to two hydrogen atoms (H).
   - The structure is shown as:
     ```
     H
     |
     C≡N:
     |
     H
     ```

3. **Ketene**:
   - Structure: A carbon (C) is double-bonded to oxygen (O) with two lone pairs of electrons and is also double-bonded to another carbon (C).
   - The second carbon is bonded to two hydrogen atoms (H).
   - Represented as:
     ```
     H
     |
     H-C=C=O:
     ```

4. **Ammonia**:
   - Structure: A nitrogen atom (N) bonded to three hydrogen atoms (H), with one lone pair of electrons on nitrogen.
   - Shown as:
     ```
      H
      |
     H-N-H
     ::
     ```

5. **Enol form of an Acetaldehyde**:
   - Structure: A carbon atom is double-bonded to another carbon, which is bonded to an OH group (hydroxyl group).
   - The first carbon is also double-bonded to an oxygen atom (O) with two lone pairs of electrons. 
   - The second carbon is singly bonded to two hydrogen atoms.
   - Represented as:
     ```
     H   O:
     |   ||
     H-C-C-C-H
     |   |
    H-C=C
     ```

The diagram accurately depicts the molecular arrangements and electron distributions, useful for understanding chemical bonding and geometry.
