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. `0.50`
B. `1.2 xx 10^(-10)`
C. `0.25`
D. `1.2`

Answer 1

Correct Answer - C
`"Partial charge " = "Dipole moment"/"Bond distance"`
` = (1.2 xx 10^(-18)"esu cm")/(1xx 10^(-8)cm) = 1.2 xx 10^(-10) "esu"`
`"Fractional charge " = (1.2 xx 10^(-10))/(4.8 xx 10^(-10)) = 0.25`
`(4.8 xx 10^(-10)" is a theoretical value of "mu )`
