Question

Pauling's equation for determining the electronegativity of an element, is ($X_A,X_B=$ electronegativity values of elements A and B , $\Delta$ = represents polarity of A - B bond)

• A. $X_A-X_B=0.208\sqrt{\Delta }$
• B. $X_A-X_B=\sqrt{\Delta }$
• C. $X_A-X_B=0.208{\Delta }^2$
• D. $X_A+X_B=0.208\sqrt{\Delta }$

Answer 1

The correct option is A $X_A-X_B=0.208\sqrt{\Delta }$

We can determine electronegativity of elements A and B using the Pauling formula,
$X_A-X_B=0.208\sqrt{\Delta }$
Hence option (a) is correct.
