The Calculation for the Molecular Position Electronegativity of Organic Molecules

The molecular position electronegativity (MPEN) is a new concept and based on the auther's studying of group electronegativity^[1,2]. MPEN represents the power of attracting an electron of the center atom situated different molecular environment. MPEN is defined as the electronegativity of the center atom situated different molecular environment and this is affectde by neighbors of the center atom.
