A

`11%`

B

`20%`

C

`25%`

D

None of these.

Text Solution

Verified by Experts

The correct Answer is:
C
`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%`

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 ? .

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.
