A. \(\text{XeO}_2\text{F}_2\)
B. \(\text{SF}_4\)
C. \(\text{BrF}_3\)
D. \(\text{XeO}_4\)
Choose the correct answer from the options given below:
- A A only
- B B only
- C A and B only
- D C, D and A only
Answer & Solution
Correct Answer
(C) A and B only
Step-by-step Solution
Detailed explanation
\( \text{For XeO}_2\text{F}_2 \): \( \text{Lone pairs (LP)} = (8 - 2 \times 2 - 2 \times 1)/2 = 1 \) \( \text{Steric Number (SN)} = 4 (\text{Bond Pairs}) + 1 (\text{LP}) = 5 \) \( \text{Shape: See-saw} \) \( \text{For SF}_4 \):…
