Chemistry Question on Classification of elements & periodicity in properties
The formula of a noble gas species which is isostructural with BrO-3 is:
A
XeOF4
B
XeF2
C
XeO3
D
XeF4
Answer
XeO3
Explanation
Solution
The formula of a noble gas species that is isostructural with BrO₃⁻ (bromate ion) is XeO₃.
Isostructural species have the same molecular or polyatomic ion structure. In this case, both BrO₃⁻ and XeO₃ have a trigonal pyramidal structure, where the central atom (Br or Xe) is surrounded by three oxygen atoms.
Therefore, the correct answer is XeO₃.
