Question

what are heteroatoms?

Answer 1

In organic chemistry, a heteroatom(from Ancient Greek heteros, different, + atomos) is any atom that is not carbon or hydrogen. Usually, the term is used to indicate that non-carbon atoms have replaced carbon in the backbone of the molecular structure.


Hetero atoms are used in organic chemistry, basically all other atom than carbon and hydrogen are known as hetero atoms. The common hetero atoms which are used in Organic chemistry are, O, N, S, P ,X ( Cl, Br, I etc.)

These hetero atoms are very useful in synthetic chemistry as they provide a series of compounds which are essential for the life as, in DNA the Nitrogen bases are used to pair and also in all the amino acids, amide group (-CONH2) is found.

They are Used as all functional groups upon which the organic chemistry and pharmaceutical chemistry depends. For ex. in Amines (NH2), In Carboxylic acids (-COOH), in acid chlorides, amides, cyanides etc.

Hey mate!

Thank you for asking this question! ❤

Answer:

___________________________________________________

• In a hydrocarbon chain, one or more Hydrogen atoms can be replaced by elements such that the valency of Carbon remains satisfied. In search compounds, the element replacing Hydrogen is referred to as a Heteroatom...

e.g. CH3CH2COOH, Propanoic acid, with a functional group —COOH, etc.

• A Functional Group(Heteroatomic molecule) is defined as the heteroatom, or the group containing them, which confer specific properties to the Carbon compound where they are present, regardless of the length and the nature of the Carbon chain. It is also the site of chemical reactivity in the organic molecule...
