Pauling's equation for determining the electronegativity of an element, is (`X_(A), X_(B)` are electronegativity value of elements A and B respectively, `Delta` represents the polarity of A-B bond.)

Options

A. `X_(A)-X_(B)=0.208sqrt(Delta)`
B. `X_(A)+X_(B)=0.208sqrt(Delta)`
C. `X_(A)-X_(B)=0.208 Delta^(2)`
D. `X_(A)-X_(B)= sqrt(Delta)`

Answer

A

Explanation

According to Pauling, `X_(A)-X_(B)=0.208sqrt(Delta)`
`or, X_(A)-X_(B)=0.208[E_(A-B)-(E_(A-A)xxE_(B-B))^(1//2)]^(1//2)`
