Chapter 3 Introduction to Organic Molecules and Functional Groups I. Functional Groups A functional group is an atom or group of atoms with characteristic chemical and physical properties. Functional groups can sometimes be classified as having polar or nonpolar properties depending on their atomic composition and organization. Polarity of a functional group depends on the difference of electronegativity of each atom, bonding nature of atoms, attached substituent/groups to Electron-withdrawing groups decrease the basicity of an amine by lessening the effect of the lone pair, while electron-donating groups increase basicity by amplifying the lone pair effect.
