Question

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 ? .
A. 12% of e
B. 18% of e
C. 25% of e
D. 29% of e

Answer 1

Correct Answer - B
`delta=("dipole moment")/d=(1.2D)/(1.0xx10^(-8)cm)`
`=(1.2xx10^(-18) "esu.cm")/(1.0xx10^(-8)"cm")`
The fraction of an electronic charge is `=(1.2xx10^(-10)"esu")/(4.8xx10^(-10) "esu/e")`
