Question

Pauling's electronegativity values for elements are useful in predicting?

• A. Polarity of the molecules
• B. Position in the electrochemical series
• C. Coordination number
• D. Dipole moments

Answer 1

The correct option is A

Polarity of the molecules

Percentage ionic character can be determined using E.N difference

% ionic character = 16 ($X_A$ - $X_B$) + 3.5 ${(X_A+X_B)}^2$,

where $X_A$ and $X_B$ are electronegativities of atoms A and B.
