Diatomic molecule has a dipole moment of...

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

Text Solution

Verified by Experts

The correct Answer is:
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")`

Polar covalent molecules exhibit dipole moment. Dipole moment is equal to the product of charge separation , q and the bond length d for the bond. Unit of dipole moment is debye. One debye is equal to 10^(-18) esu cm. Dipole moments is a vector quantity. It has both magnitude and direction. Hence, dipole moment of a molecule depends upon the relative orientation of the bond dipoles, but not on the polarity of bonds alone. A symmetrical structure shows zero dipole moment. Thus, dipole moment helps to predict the geometry of a molecules. Dipole moment values can be distinguish between cis- and trans- isomers, ortho, meta and pare-forms of a substance, etc. Q.
