In the following sets of resonance forms, label the major and minor contributors and state which structures would be of equal energy. Add any missing resonance forms.
`[CH_(3) - CH_(2) - underset(+)overset(NH_(2))overset(|)C - NH_(2) hArr CH_(3) - CH_(2) - overset(NH_(2))overset(|)C = overset(+)NH_(2)]`

Explanation

To analyze the resonance forms provided in the question, we will follow these steps:

### Step 1: Identify the Resonance Forms
We have the following resonance forms:
1. **Form 1**: \( CH_3 - CH_2 - \overset{+}{N} \overset{|}{C} - NH_2 \)
2. **Form 2**: \( CH_3 - CH_2 - \overset{|}{C} = \overset{+}{NH_2} \)

### Step 2: Add Missing Resonance Form
