Diatomic molecule has a dipole moment of `1.2D` If its bond `1.0 Å` what fraction of an electronic charge exists on each atom ? .

Options

A. `11%`
B. `20%`
C. `25%`
D. None of these.

Answer

C

Explanation

`mu=qxxd=4.8xx10^(-12)esuxx10^(-8)cm`
`=4.8xx10^(-18)esu cm`
`=4.8D`
`%` ionic character
`=(mu_(obs))/(mu_(th))xx100=(1.2)/(4.8)xx100=25%`
