Question:
Which of the following interhalogen compounds is used in the determination of iodine value of an oil?
Which of the following interhalogen compounds is used in the determination of iodine value of an oil?
Show Hint
The iodine value of an oil is found using Wijs reagent.
Updated On: Nov 13, 2026
- \(ICl_3\)
- \(ICl\)
- \(IF_3\)
- \(IF_7\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
The iodine value measures the unsaturation of an oil. It is determined using Wijs solution, which is iodine monochloride in glacial acetic acid.
Step 2: Identify the Compound
Iodine monochloride is \(\text{ICl}\); it adds across the C=C bonds of the oil.
Step 3: Compare the options
The interhalogen compound used is \(\text{ICl}\), option (B).
Final Answer:
ICl is used to find the iodine value of an oil. \[ \boxed{\text{(B) }ICl} \]
