Assertion : The dipole moment helps to ...

Assertion : The dipole moment helps to predict whether a molecule is polar or non- polar.
Reason : The dipole moment helps to predict geometry of molecule.

A

If both assertion and reason are true and the reason is a true explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

if assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
a
The linear triatomic moulas of the type B-A-B e.g. `CO_(2)` have no dipole moment not because the individual `C = O` bonds are non- polar but because the two bond moment (polarity) cancel each other .Therefore , gemoetry of molecule can be predicted by the value of dipole moment .

The order of dipole moment of the following molecules is

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. Which is a polar molecule?
