What are specific chemical properties of heteroatom and what is heteroatom?

Hint: There are two significant bonding highlights that produce the reactive sites of functional groups. The main, as of now referenced, is the presence of multiple bonds. Both double and triple bonds have areas of high electron density lying outside the atom-to-atom bond axis. Double and triple bonds are known as functional groups, a term that is utilized to distinguish atoms or groups of atoms inside a particle that are sites of similarly high reactivity. A second kind of reactive site results when an atom other than carbon or hydrogen (named a heteroatom) is bonded to carbon

Complete step by step answer:
The atoms that are different from hydrogen and carbon are called heteroatoms.
Chemical properties:
1) The impact on reactivity of \[\alpha - hydrogens\] in the hydroperoxide chain mechanism regarding electron supply and withdrawal
(2) The impact on α-hydrogen acidity in base-catalyzed oxidation
 (3) The impact on radical particle stability in base-catalyzed redox chains
 (4) The possibility of heteroatom hydrogen bond attack and subsequent reaction of the subsequent heteroradical
 (5) The chance of radical attack on higher column components through valence expansion
(6) The chance of radical expansion to electron-deficient II and III group atoms

Note:
All heteroatoms have a more noteworthy or lesser attraction for electrons than does carbon. Thus, each bond between a carbon and a heteroatom is polar, and the level of polarity relies upon the contrast between the electron-attracting properties of the two atoms. The main atomic groupings that contain such reactive polar bonds are additionally ready to produce functional groups.
