- F
- Cl
- Br
- I
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Halogens (except Fluorine) form various oxoacids due to their ability to expand their octet.
Step 2: Analysis
- **Chlorine (Cl):** Forms 4 oxoacids ($HClO, HClO_2, HClO_3, HClO_4$). - **Bromine (Br):** Forms 3 oxoacids ($HBrO, HBrO_3, HBrO_4$). - **Iodine (I):** Forms 3 oxoacids ($HIO, HIO_3, HIO_4$). - **Fluorine (F):** Forms only 1 oxoacid ($HFO$) due to high electronegativity and lack of d-orbitals.
Step 3: Conclusion
Chlorine forms the maximum number of stable oxoacids.
Final Answer: (B)
