Question

Which of the following statements are correct? I. Reaction of bromine with excess fluorine gives a T-shaped compound. II. Iodine oxides decompose on heating. III. Roasting of sulphide ores gives \(\mathrm{SO_2}\) as a byproduct. The correct answer is

• A. I, II only
• B. II, III only
• C. I, III only
• D. I, II, III

Hint:

Remember: \[ \boxed{ \mathrm{BrF_3} \rightarrow \text{T-shaped} } \] \[ \boxed{ \mathrm{BrF_5} \rightarrow \text{Square pyramidal} } \] Roasting of sulphide ores always liberates \[ \boxed{\mathrm{SO_2}.} \]

Answer 1

The Correct Option is B
