Use the following table to rank these bonds in order of decreasing bond length:
Bond/Bond strength:
HH:436
ClCl:243
HBr:366
HN:391
II:151
CI:216
Rank them in Longest to Shortest bond length.
The dipole moment, meu, of HBr (a polar covalent molecule) is 0.82 D (debye), and its percent ionic character is 12.1%. Estimate the bond length of the HBr bond in picometers.
1 D = 3.34 * 10^30 C*m
in a bond with 100% ionic character, q = 1.6 * 10^19 C

The dipole moment m is equal to the charge in coulombs times the bond distance in meters. m = D x R The result would be in coulombsmeters. To convert to debyes, divide by 3.34×10^30
