Halogen bonding lengths

Table 6.1 Carbon-Halogen Bond Lengths, Bond Strength and Dipole Moment...

Since the size of halogen atom Increases as we go down the group in the periodic table, fluorine atom is the smallest and iodine atom, the largest. Consequently the carbon-halogen bond length also Increases from C—to C— I. Some typical bond lengths, bond enthalpies and dipole moments are given in Table 10.2.

For dichloro1092 and diiodo356 diorganotin adducts, considerable evidence exists for Sn-halogen bond length differences between the cis and trans arrangements, the former having shorter distances. 

The carbon-halogen bond lengths increase as the halogen atoms become bigger (larger atomic radii) in the order... 

In spite of the absence of many examples, the ascending sequence for primary, secondary and tertiary carbon-halogen bond lengths is apparent thus, for C—Cl bonds, CHaCHjCK/i = 1.788 0.002 A), >...

Halogen atom size increases as we go down the periodic table fluorine atoms are the smallest and iodine atoms the largest. Consequently, the carbon-halogen bond length increases and carbon-halogen bond strength decreases as we go down the periodic table (Table 6.1).
