Group electronegativities

Group electronegativities

Introduction

Although electronegativity according to its original definition by Pauling is a property of an element it is such a useful concept that attempts have been made to apply it to functional groups as well. The electronegativity of functional groups can be estimated using a number of different approaches. The values shown here are computed using the assumption of electronegativity equalization.
They can be seen as a complement to Hammett-type parameters when describing functional group polarity but are less versatile.
