Question

Which among the following pairs of halogen forms the interhalogen compound of the type XX'Y?

• A. Br and F
• B. Cl and F
• C. I and F
• D. I and Cl

Hint:

Interhalogen compounds can be of the type XX'Y, where X and X' are halogens, and Y is another halogen. The halogen combinations I and F form compounds like IF\(_5\) and IF\(_3\).

Answer 1

The Correct Option is C

Step 1: Understanding interhalogen compounds.
Interhalogen compounds are compounds formed by the combination of two halogens. They can take the form XX'Y, where X and X' are halogens, and Y can be another halogen.

Step 2: Analyzing the options.
(A) Br and F: This combination forms BrF, which is an interhalogen compound but not of the form XX'Y.
(B) Cl and F: This combination forms ClF, but this is not of the form XX'Y.
(C) I and F: This combination forms IF\(_5\) and IF\(_3\), both of which are interhalogen compounds of the type XX'Y.
(D) I and Cl: This combination forms ICl, which is an interhalogen compound, but not in the XX'Y form.

Step 3: Conclusion.
The correct answer is (C) I and F, which forms interhalogen compounds of the type XX'Y.
