Give the correct order of initials T or F for following statements. Use T if statements is true and F if if false.
`(I)` Number of `S-S` bond in `H_(2)S_(n)O_(6)` are `(n+1)`
`(II)` When `F_(2)` reacts with water gives `HF,O_(2)` and `O_(3)`
`(III)` `LiNO_(3)` and `BaCl_(2)` compounds are used in the fire works
`(IV)` Be and Mg hydrides are ionic and polymeric

Options

A. FTTF
B. FTTT
C. TFTT
D. TTFF

Explanation

To determine the truth value of each statement, we will analyze them one by one.

### Step 1: Analyze Statement (I)
**Statement (I)**: The number of S-S bonds in H₂SₙO₆ are (n + 1).

- In the compound H₂SₙO₆, the number of S-S bonds is actually (n - 1). This is because each sulfur atom can bond with another sulfur atom, and for n sulfur atoms, there will be (n - 1) S-S bonds.
- **Conclusion**: This statement is **False (F)**.

### Step 2: Analyze Statement (II)
**Statement (II)**: When F₂ reacts with water, it gives HF, O₂, and O₃.

- F₂ reacts vigorously with water to produce hydrogen fluoride (HF) and oxygen (O₂). In some cases, it can also produce ozone (O₃) instead of oxygen.
- The reactions can be summarized as:
- 2F₂ + 2H₂O → 4HF + O₂ (major reaction)
- 3F₂ + 3H₂O → 6HF + O₃ (minor reaction)
- **Conclusion**: This statement is **True (T)**.

### Step 3: Analyze Statement (III)
**Statement (III)**: LiNO₃ and BaCl₂ compounds are used in fireworks.

- LiNO₃ is known to produce a crimson red color in fireworks, while BaCl₂ produces a green color.
- Both compounds are indeed used in pyrotechnics for their color-producing properties.
- **Conclusion**: This statement is **True (T)**.

### Step 4: Analyze Statement (IV)
**Statement (IV)**: Be and Mg hydrides are ionic and polymeric.

- Beryllium (Be) and magnesium (Mg) hydrides are actually covalent in nature, not ionic. They are also polymeric in structure.
- Therefore, the statement that they are ionic is incorrect.
- **Conclusion**: This statement is **False (F)**.

### Final Summary
Based on the analysis, we can summarize the truth values of the statements as follows:
- **(I)**: F
- **(II)**: T
- **(III)**: T
- **(IV)**: F

### Final Answer
The correct order of initials is: **F, T, T, F**.
