Explanation

To draw the structure of cis-bis(propenyl)ethene, follow these steps:

### Step 1: Understand the components of the name
- **Ethyne**: This is a two-carbon alkyne (C≡C).
- **Propenyl**: This refers to the propenyl group (C3H5), which is derived from propene (C3H6) by removing one hydrogen atom.

### Step 2: Draw the ethene backbone
- Start with the ethene structure, which is a double bond between two carbon atoms:
```
H2C = CH2
```

### Step 3: Identify the cis configuration
- The term "cis" indicates that the substituents (in this case, the propenyl groups) are on the same side of the double bond.

### Step 4: Add the propenyl groups
- Attach two propenyl groups (C3H5) to the ethene structure. Since it is "cis-bis(propenyl)", both propenyl groups will be on the same side of the ethene double bond.
- The propenyl group can be represented as:
```
H2C = CH - CH2
```

### Step 5: Combine the structures
- The final structure will look like this:
```
H2C
|
H2C = C - CH2
|
CH2
```

### Final Structure
- The complete structure of cis-bis(propenyl)ethene can be represented as:
```
H2C
|
H2C = C - CH2
|
CH2
