Factors that Influence the Electronic Nature of Bonds and Atoms

Factors that Influence the Electronic Nature of Bonds and Atoms 

All effects that influence the electron density in a specific part of a molecule strongly affect the chemical reactivity of that part. While - for example - electron-rich parts show hardly any reactivity against HO, electron-poor parts will easily react with this strong electron-donor.

The most important effects that influence the electron density of specific parts of a molecule are the inductive and conjugative effects.
