Which of the following interaction lies in the range of 8-42kH/mol?

Options

A. `H_(2)..H_(2)O`
B. `HCl..HCl`
C. `F^(-)…HF`
D. `HCN…NH_(3)`

Explanation

To determine which interaction lies in the range of 8-42 kJ/mol, we will analyze each of the given options based on the type of interactions they represent and the energy associated with those interactions.

### Step-by-Step Solution:

1. **Identify the Interactions:**
- We have four options:
- A: H2O and H2
- B: HCl and HCl
- C: F- and HF
- D: HCN and NH3

2. **Analyze Option A (H2O and H2):**
- The interaction between H2O and H2 is a dipole-induced dipole interaction.
- This type of interaction typically requires energy of less than 8 kJ/mol.
- **Conclusion:** This is not the correct answer.

3. **Analyze Option B (HCl and HCl):**
- The interaction here is a dipole-dipole interaction.
- Dipole-dipole interactions also require energy of less than 8 kJ/mol.
- **Conclusion:** This is not the correct answer.

4. **Analyze Option C (F- and HF):**
- This interaction is an ion-dipole interaction.
- Ion-dipole interactions generally require energy greater than 42 kJ/mol.
- **Conclusion:** This is not the correct answer.

5. **Analyze Option D (HCN and NH3):**
- The interaction between HCN and NH3 is a hydrogen bond.
- Hydrogen bonds typically require energy in the range of 8-42 kJ/mol.
- **Conclusion:** This is the correct answer.

### Final Answer:
The interaction that lies in the range of 8-42 kJ/mol is **Option D: HCN and NH3**.
