### Structural Formula Bond Evaluation Problem

One, or both, of the following structural formulas may be incorrect (i.e., they do not represent a real compound) because they have atoms with an incorrect number of bonds. Which of the labeled atoms have the incorrect number of bonds?

**Instructions:**
Specify the incorrect atoms by letter in alphabetical order without spaces or commas, i.e., bd.  
If there are no incorrect atoms, write none.

#### Structural Formulas:

**a)**
```
  H   H       H  H
 N---C---C---C---O 
 |       |   |   ||
 H       H   H    O
 a       b   c    d
```

**b)**
```
      H          O  
      |          | 
  H   N===C===C---O 
  |   |   |   |   | 
  H   b   a   c   d
      H
```

**Discussion:**
- Structural formula **a** shows a linear arrangement of atoms labeled a, b, c, and d. Each carbon (C), nitrogen (N), hydrogen (H), and oxygen (O) is connected via single or double bonds.
- Structural formula **b** shows a linear arrangement of atoms labeled a, b, c, and d, with multiple bonds between certain atoms.

**How to Approach the Problem:**
1. **Identify the Standard Bonding for Each Atom:**
   - Hydrogen (H) forms 1 bond.
   - Carbon (C) forms 4 bonds.
   - Nitrogen (N) forms 3 bonds.
   - Oxygen (O) forms 2 bonds.
2. **Count the Bonds for Each Labeled Atom in Both Formulas.**
3. **Compare the Counted Bonds with the Standard Bonding Requirements.**

**Answer Boxes:**
- ***Formula a:***
- ***Formula b:***

By analyzing the structures as described, you can determine if any atoms are incorrect in their bond count and provide the specified results in the answer boxes.
