Q. Pauling’s equation for determining the electronegativity of an element, is $X_{A},\ X_{B} =$electronegativity values of elements $A$ and $B$ $\mathrm{\Delta} =$represents polarity of $A - B$ bond
A) $X_{A} - X_{B} = 0.208\sqrt{\mathrm{\Delta}}$
B) $X_{A} + X_{B} = 0.208\sqrt{\mathrm{\Delta}}$
C) $X_{A} - X_{B} = 0.208\mathrm{\Delta}^{2}$
D) $X_{A} - X_{B} = \sqrt{\mathrm{\Delta}}$
Explanation
(a)
Pauling scale is based upon the excess bond energies. Pauling equation for determining the electronegativity of an element is
$X_{A} - X_{B} = 0.208\sqrt{\mathrm{\Delta}}$
where, $X_{A},\ X_{B} =$electronegativity values of elemnt A and B
$\mathrm{\Delta}$=polarity of $A - B$ bond.
