Neoprene is a polymer of

Options

A. chloroprene
B. chloroquine
C. propylene
D. isoprene

Answer

To determine the polymer of neoprene, we need to identify its monomer unit. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Monomer of Neoprene
Neoprene is a synthetic rubber, and its monomer unit is known as chloroprene. The chemical structure of chloroprene can be represented as:
\[ \text{CH}_2 = \text{C}(\text{Cl}) - \text{CH} = \text{CH}_2 \]

### Step 2: Understand the Polymerization Process
When chloroprene undergoes polymerization, the double bonds in its structure open up, allowing the monomers to link together to form the polymer known as neoprene.

### Step 3: Confirm the Correct Answer
Given the options, we need to confirm that chloroprene is indeed the correct monomer for neoprene. Other options such as chloroquinone and isoprene do not lead to neoprene upon polymerization.

### Conclusion
Thus, the correct answer is that neoprene is a polymer of chloroprene.
