Lyophobic colloids show

Options

A. no interaction with the dispersion medium
B. Medium interctions with the dispersion medium
C. Strong interaction with the dispersion medium.
D. Less interaction with the dispersion medium.

Answer

**Step-by-Step Solution:**

1. **Understanding Lyophobic Colloids:**
- Lyophobic colloids are defined as "liquid-hating" colloids. The term "lyo" refers to solvent, and "phobic" means hating. Therefore, lyophobic colloids do not interact favorably with the dispersion medium (solvent).

2. **Characteristics of Lyophobic Colloids:**
- When lyophobic colloids are mixed with a suitable liquid, they exhibit a significant lack of interaction with the dispersion medium. This means that the colloidal particles do not have a strong attraction to the solvent.

3. **Analyzing Options:**
- Given the nature of lyophobic colloids, we can analyze the provided options:
- **Option 1:** No interaction with the dispersion medium - This is correct as lyophobic colloids do not interact favorably with the solvent.
- **Option 2:** Medium interaction with the dispersion medium - This is incorrect.
- **Option 3:** Strong interaction with the dispersant medium - This is incorrect.
- **Option 4:** Strong interaction with lyophilic colloids - This is incorrect.
- **Option 5:** Less interaction with the dispersant medium - This is misleading as it implies some interaction exists, which is not the case for lyophobic colloids.

4. **Conclusion:**
- The correct answer is **Option 1: No interaction with the dispersion medium**, as lyophobic colloids are characterized by their lack of interaction with the solvent.
