The dipole moments of diatomic molecules...

The dipole moments of diatomic molecules AB and CD are 10.41D and 10.27 D, respectively while their bond distances are 2.82 and `2.67Å` respectively. This indicates that

A

Bonding is 100% ionic in both the molecules.

B

AB has more ionic bond character than CD.

C

AB has lesser ionic bond charater than CD.

D
