Answer:

Well, for a start consider the strength of the #C-I# bonds versus the #C-F# bond.........

Explanation:

You will have to look in text for this, in that I cannot find a useful table on the interwebz. However, it is a fact that the #C-F# bond is MUCH stronger than the #C-I# bond, and that, therefore, #C-I# should undergo substitution more readily via dissociative OR associative mechanisms.

Answer:

R-I bond is more reactive than R-F

Explanation:

  • F and I are from same group.
  • F comes first and then I.
    F
    Cl
    Br
    I
    At
    Due to strong nuclear charge in case of F , F has high electron affinity than I.Thus,R-I is more reactive than R-F.
    = to free electron easily
