what is functional group?
Answers
hello good morning
In organic chemistry, functional groups are specific substituents or moieties within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of.
Functional group may be defined as an atom or group of atoms or reactive part which is responsible for the characteristic properties of the compounds.The chemical properties of organic compounds are determined by the functional groups while their physical properties are determined by the remaining part of the molecule.
Example:(-OH )= Alcohol
(-CHO)=Aldehyde
(-COOH)= Carboxylic acid
(C=O. )= Ketone
