Rayon and cellophane are formed of

Options

A. Cellulose xanthate
B. Cellulose nitrate
C. Cellulose acetate
D. Carboxymethyl cellulose.

Answer

**Step-by-Step Solution:**

1. **Understanding the Components**: Rayon and cellophane are both derived from cellulose, which is a polysaccharide made up of glucose units linked by beta-1,4-glycosidic bonds. Cellulose is a major component of plant cell walls.

2. **Identifying the Chemical Process**: The production of rayon and cellophane involves a chemical reaction where cellulose reacts with carbon disulfide in the presence of sodium hydroxide. This reaction leads to the formation of cellulose xanthate.

3. **Neutralization Reaction**: After the formation of cellulose xanthate, it is then neutralized with sulfuric acid (H2SO4). This step is crucial as it transforms cellulose xanthate into rayon and cellophane.

4. **Choosing the Correct Option**: Among the given options:
- Cellulose terephthalate
- Cellulose nitrate
- Cellulose acetate
- Carboxymethyl cellulose

The correct answer is cellulose xanthate, which is not listed but is the precursor to both rayon and cellophane.

5. **Conclusion**: Therefore, rayon and cellophane are formed from cellulose through a series of chemical reactions involving carbon disulfide and sulfuric acid.

**Final Answer**: Rayon and cellophane are formed from cellulose xanthate.
