Write true or false :Both red and white phosphorous are soluble in `CS_2`.

Explanation

To determine whether the statement "Both red and white phosphorus are soluble in carbon disulfide (CS2)" is true or false, we can analyze the solubility characteristics of both forms of phosphorus.

### Step-by-Step Solution:

1. **Identify the Characteristics of White Phosphorus:**
- White phosphorus is a soft and waxy solid.
- It has a characteristic garlic smell.
- It is poisonous.
- White phosphorus is insoluble in water but is soluble in carbon disulfide (CS2).

2. **Identify the Characteristics of Red Phosphorus:**
- Red phosphorus is a hard and crystalline solid.
- It has no distinct smell.
- It is non-poisonous.
- Red phosphorus is insoluble in water and also insoluble in carbon disulfide (CS2).

3. **Analyze the Given Statement:**
- The statement claims that both red and white phosphorus are soluble in carbon disulfide (CS2).
- From our analysis, we found that while white phosphorus is soluble in CS2, red phosphorus is not.

4. **Conclusion:**
- Since red phosphorus is not soluble in carbon disulfide, the statement "Both red and white phosphorus are soluble in CS2" is **false**.

### Final Answer:
**False**
