The monomer of acrilon is

Options

A. vinyl cyanide
B. vinyl chloride
C. vinyl bromide
D. vinyl alcohol

Explanation

To determine the monomer of acrylon, we need to identify the correct compound that polymerizes to form acrylonitrile. Here’s a step-by-step solution:

### Step 1: Identify the options
The options provided are:
1. Vinyl cyanide
2. Vinyl chloride
3. Vinyl bromide
4. Vinyl alcohol

### Step 2: Understand the term "monomer"
A monomer is a small molecule that can join together with other similar molecules to form a polymer. In this case, we are looking for the monomer that forms acrylonitrile.

### Step 3: Analyze the structure of acrylonitrile
Acrylonitrile is also known as vinyl cyanide. Its chemical structure can be represented as CH2=CH-CN, where:
- CH2=CH represents the vinyl group.
- CN represents the cyano group.

### Step 4: Identify the correct monomer
From the options given, vinyl cyanide (option 1) is the correct monomer that polymerizes to form acrylonitrile. The polymerization of vinyl cyanide leads to the formation of polyacrylonitrile.

### Step 5: Write the polymerization reaction
The polymerization reaction can be represented as follows:
- n CH2=CH-CN (vinyl cyanide) → (–CH2–CH(CN)–)n (polyacrylonitrile)

### Conclusion
The monomer of acrylon is **vinyl cyanide**.

### Final Answer
**A. Vinyl cyanide**
