Which among the following forms a linear polymeric structure due to hydrogen bonding?

Options

A. Hydrogen sulphide
B. Hydrogen fluoride
C. Hydrogen sulphate
D. Both (a) and (b)

Explanation

To determine which compound forms a linear polymeric structure due to hydrogen bonding, we need to analyze the options provided.

### Step-by-Step Solution:

1. **Understanding Hydrogen Bonding**:
- Hydrogen bonding occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (like N, O, or F) and is attracted to another electronegative atom. This interaction can lead to the formation of linear or branched polymeric structures.

2. **Analyzing the Compounds**:
- Let's consider the compounds mentioned:
- **H2S (Hydrogen Sulfide)**: Sulfur is not highly electronegative, so hydrogen bonding is weak or absent.
- **HF (Hydrogen Fluoride)**: Fluorine is highly electronegative, allowing for strong hydrogen bonding. HF can form linear chains due to these hydrogen bonds.
- **H2SO4 (Sulfuric Acid)**: While it can participate in hydrogen bonding, it does not typically form a linear polymeric structure.

3. **Identifying the Linear Polymeric Structure**:
- Among the compounds analyzed, **HF** is the only one that can form a linear polymeric structure due to the strong hydrogen bonding between HF molecules.

4. **Conclusion**:
- Therefore, the compound that forms a linear polymeric structure due to hydrogen bonding is **HF (Hydrogen Fluoride)**.
