Questions
ICl is more reactive than I2.
Explain why:
ICI is more reactive than I2.

Solution 1
The I-Cl bond in ICl is weaker than the I-I bond in I2. Therefore, ICl is more reactive than I2.
Solution 2
ICI is more reactive than I2 because ICl is polar and has lower bond energy than I2 (non-polar).
Solution 3
- ICl has a polar bond due to the difference in electronegativity between iodine and chlorine, making it more reactive.
- I2 has a nonpolar I-I bond which is stronger and less reactive.
- The I-Cl bond in ICl is weaker than the I-I bond in I2, so it breaks more easily.
- ICl acts as a better halogenating agent due to its polarity and weaker bond.
Thus, ICl is more reactive than I2.
