Which of the following has glycol as in important constituent?

Options

A. Dacron
B. Acrilian
C. Teflon
D. Visocose

Answer

To determine which of the following options has glycol as an important constituent, let's analyze each option step by step.

### Step 1: Identify the options
The options provided are:
1. Dacron
2. Acrylene
3. Teflon
4. Viscose

### Step 2: Analyze each option

**Option 1: Dacron**
- Dacron is a type of polyester, specifically made from the polymerization of ethylene glycol and terephthalic acid.
- Since ethylene glycol is a key component in Dacron, it qualifies as having glycol as an important constituent.

**Option 2: Acrylene**
- Acrylene is a synthetic fiber made from acrylonitrile, which is derived from acetylene and hydrogen cyanide.
- It does not contain glycol as a constituent.

**Option 3: Teflon**
- Teflon is a synthetic polymer made from carbon and fluorine atoms (specifically polytetrafluoroethylene).
- It does not have glycol as a component.

**Option 4: Viscose**
- Viscose is a man-made fiber derived from cellulose, which is obtained from wood pulp.
- There is no glycol involved in the production of viscose.

### Step 3: Conclusion
After analyzing all options, we find that only Dacron contains glycol as an important constituent.

**Final Answer:** The correct option is **Dacron**.
