If the starting material for the manufacture of silicone is `RSiCl_(3)`, write the structure of the product formed.

Answer

To solve the problem of determining the structure of the product formed from the starting material \( RSiCl_3 \), we can follow these steps:

### Step 1: Identify the Starting Material
The starting material is \( RSiCl_3 \), where \( R \) represents an organic group (which can be an alkyl or aryl group) and \( SiCl_3 \) indicates that silicon is bonded to three chlorine atoms.

### Step 2: Reaction with Water
When \( RSiCl_3 \) reacts with water (\( H_2O \)), a hydrolysis reaction occurs. The chlorine atoms are replaced by hydroxyl groups (\( OH \)). The reaction can be represented as follows:

\[ RSiCl_3 + 3 H_2O \rightarrow RSi(OH)_3 + 3 HCl \]

This means that the product formed after hydrolysis is \( RSi(OH)_3 \), which is a silanol.

### Step 3: Structure of the Silanol
The structure of the silanol \( RSi(OH)_3 \) can be depicted as follows:

```
OH
|
R - Si - OH
|
OH
```

### Step 4: Polymerization
The silanol \( RSi(OH)_3 \) can undergo condensation reactions, leading to polymerization. During this process, water is eliminated, and siloxane bonds (\( Si-O-Si \)) are formed. The general structure of the polymer can be represented as:

\[ \text{(RSi-O)}_n \]

Where \( n \) indicates the number of repeating units. The polymer can be depicted as follows:

```
R R R
\ / \
Si - O - Si - O - Si - O - ...
/ \ /
R R R
```

### Final Product Structure
The final product is a silicone polymer, which can be represented as:

```
R R R
\ / \
Si - O - Si - O - Si - O - ...
/ \ /
R R R
```

This structure shows the repeating units of silicon and oxygen, with organic groups \( R \) attached to the silicon atoms.

### Summary
The product formed from the starting material \( RSiCl_3 \) after hydrolysis and polymerization is a silicone polymer with a structure that consists of alternating silicon and oxygen atoms, with organic groups attached to the silicon.
