Use the following table to rank these bonds in order of decreasing bond length:
Bond/Bond strength:
H-H:436
Cl-Cl:243
H-Br:366
H-N:391
I-I:151
C-I: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 H-Br 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 coulombs-meters. To convert to debyes, divide by 3.34×10^-30
