Functional groups determine the chemical reactivity of an organic molecule. The gas can be tested by a moist red litmus paper which is then turned blue. If you are a science student, then you must have covered this topic in chemistry classes. Most of the time in organic chemistry, you will have one reactant with a functional group, a reagent will be added, and then your product will have a new functional group. The other organic compounds are derived from hydrocarbons by replacement of one or more hydrogen atoms by other atoms or group of atoms (functional group) such as —OH, —CHO, —COOH, —Cl, etc. You can review them and learn them easily enough! Functional groups are specific substituents within molecules that are responsible for the characteristic chemical reactions of those molecules. characterizing unknown organic compounds functional group and their solubilities. This Manual will be helpful as a hand note for the undergraduate students (B.Sc. Various books havedifferent approaches, but a systematic approach based on thescheme given below will give good results. Functional groups are responsible for the characteristics of a molecule. Identification of functional groups by test-tube reactions. They may be –OH, -COOH, -CO, -CHO, -Cl, -COCl, -COOR etc. Development of analytical skill an Practice problems are also included.
