Question

hi friends! what is a functional group in chemistry.plzz answer​

Answer 1

Answer:

Functional group: A group of atoms whose bonding is the same from molecule to molecule. A functional group has similar behavior regardless of the molecule that contains it, so molecules with identical functional groups tend to have similar chemical and physical properties. In addition, functional groups with similar structures tend to impart similar chemical and physical properties to the molecules which contain them.

Answer 2

Answer:

In organic chemistry, functional groups are specific substituents or moieties within molecules that may be 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
