Draw the resonance structures for the following compounds. Show the electron shift using curved-arrow notation.
`CH_3 CH =CH overset(+ )CH_2`

Explanation

To draw the resonance structures for the compound \( \text{CH}_3 \text{CH}=\text{CH}^+\text{CH}_2 \), we will follow these steps:

### Step 1: Identify the structure and charges
The given compound is \( \text{CH}_3 \text{CH}=\text{CH}^+\text{CH}_2 \). Here, we have a double bond between the second and third carbon atoms, and a positive charge on the third carbon atom.

### Step 2: Draw the initial structure
We can represent the structure as follows:
```
