Each of the following is true for white and red phosphorus except that they

Options

A. 1. are both soluble in `CS_(2)`
B. 2. can be oxidized by heating in air
C. 3. consist of the same kind of atoms
D. 4. can be converted into one another.

Explanation

To solve the question regarding the properties of white and red phosphorus, we need to analyze the statements provided and identify which one is false.

### Step-by-Step Solution:

1. **Understanding the Forms of Phosphorus**:
- White phosphorus (P4) consists of tetrahedral molecules and is known for its high reactivity.
- Red phosphorus is a network solid, consisting of chains of phosphorus atoms and is less reactive than white phosphorus.

2. **Analyzing the Statements**:
- **Statement 1**: Both are soluble in water.
- **Statement 2**: Both can be oxidized by heating in air.
- **Statement 3**: They consist of the same kinds of atoms.
- **Statement 4**: They can be converted into one another.

3. **Evaluating Each Statement**:
- **Solubility in Water**:
- White phosphorus is insoluble in water but soluble in non-polar solvents like carbon disulfide (CS2).
- Red phosphorus is also insoluble in water and does not dissolve in carbon disulfide.
- Thus, the statement that both are soluble in water is **false**.

- **Oxidation by Heating in Air**:
- Both white and red phosphorus can be oxidized when heated in air, so this statement is **true**.

- **Same Kinds of Atoms**:
- Both forms consist of phosphorus atoms, so this statement is **true**.

- **Conversion**:
- White phosphorus can be converted into red phosphorus through heating and other processes, making this statement **true**.

4. **Conclusion**:
- The only statement that is false is that both white and red phosphorus are soluble in water. Therefore, the answer to the question is that they are not both soluble in water.

### Final Answer:
The statement that is false regarding white and red phosphorus is that they are both soluble in water.
