If the dipole moment of AB molecules is given by 2.4 D and A-B the bond length is 1 Å than % covalent character of the bond is :

Answer

`50%`

Explanation

`N_("cal".)=4.8xx10^(-10)e.s.uxx10^(-8)`cm
`=4.8xx10^(-18)`esu cm
=4.8 D
`:.` % ionic character `=2.4/4.8xx100=50%`
`:.` % co-valent character =50%
