Functional Groups are the substituent atoms or group of atoms that attach to a molecule and enable them to participate in specific chemical reactions. Functional groups include hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.

Functional groups are collections of atoms that attach the carbon skeleton of an organic molecule and confer specific properties. Each type of organic molecule has its own specific type of functional group. Functional groups in biological molecules play a

Functional Group: Functional group is a group of an atom or atoms in any carbonic compound which are bonded each other in special manner. That is generally region of chemical reactivity in carbonic atoms. Oxygen, chlorine, sulpher, nitrogen and other elem
