Correct expression of "allred and Rochow's " scale is :

Options

A. electronegativity`=0.744(Z_(eff))/(r^(2))+0.359`
B. Electronegativity `=0.359(r^(2))/(Z_(eff))+0.744`
C. Electronegativity`=0.359(Z_(eff))/(r)+0.744`
D. Electronegativity=`0.359(Z_(eff))/(r^(2))+0.744`

Answer

D

Explanation

According to allred and rochow scale
(C) `EN_((AR))=0.359(Z_(eff))/(r)+0.744` (r: radius in Å)
