The idea which prompted bartlett to prepare first ever compound of noble gas was

Options

A. high bond energy of `Xe-F`
B. low bond energy of `F-F` in `F_(2)`
C. ionisation energies of `O_(2)` and xenon were almost similar
D. none of the above

Answer

To solve the question regarding the idea that prompted Bartlett to prepare the first-ever compound of a noble gas, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Identify the Scientist**: The scientist in question is Neil Bartlett, who is known for his work with noble gases.

2. **Understand the Compound Prepared**: Bartlett prepared a compound with the formula \( O_2^+ \) and \( PF_6^- \). This compound is significant because it was the first compound formed from a noble gas.

3. **Analyze Ionization Energies**: Bartlett noted that the ionization energy of \( O_2^+ \) (1175 kJ/mol) was very close to that of xenon (Xe), which was 1170 kJ/mol. This similarity in ionization energies was crucial.

4. **Draw a Conclusion**: Based on the similarity in ionization energies, Bartlett hypothesized that if a compound could be formed with \( O_2^+ \), then a similar compound could be formed with xenon.

5. **Formation of the Noble Gas Compound**: Following this reasoning, Bartlett successfully synthesized the compound \( Xe^+ \) and \( PF_6^- \), which was the first noble gas compound.

6. **Final Answer**: The idea that prompted Bartlett to prepare the first-ever compound of a noble gas was the observation that the ionization energies of \( O_2 \) and \( Xe \) were almost similar.

### Conclusion:
Thus, the answer to the question is that the ionization energies of \( O_2 \) and \( Xe \) were almost similar, which led Bartlett to believe that a compound could be formed with xenon as well.
