Pauling's electronegativity values for elements are useful in predicting

A

polarity of the molecules

B

position in the emf series

C

coordination numbers

D

dipole moments

Text Solution

Verified by Experts

The correct Answer is:
A
Pauling's electronegativity values are useful in determination of polarity of the bond in molecules. If electronegativity difference is zero, then the molecule is non-polar otherwise it is polar.
`X_(A)` and `X_(B) = 0.028sqrt(DeltaE)`
A and B respectively .While
`DeltaE` = actual bond energy `-sqrt(E_(A-A) xx E_(B-B))`
