Key differences in Organic Inorganic and Analytical Chemistry

Key differences in Organic, Inorganic and Analytical Chemistry

Chemistry is a branch of science which deals with study of substance and substance change and reacts with other substance to give a new substance, In Chemistry there are so many branches like Organic, Inorganic, Physical, Analytical, Green Chemistry, Nano chemistry, Biochemistry and so on.... but today we are going to discuss difference between only three Branches

Ø  Organic Chemistry

Ø  Inorganic Chemistry

Ø  Analytical Chemistry

Organic Chemistry and inorganic chemistry: -Organic Chemistry is the branch of Chemistry which deals with study of carbon and hydrogen its compounds other than salt like Oxides Carbonates. Inorganic Chemistry is the branch of Chemistry which deal with study of synthesis, Characterization, identifying behavior of Inorganic compounds and organometallic Compounds. Structure is the main difference between Organic and Inorganic Chemistry, an organic compound must have carbon, other some elements also present in organic compounds Like Nitrogen, Oxygen, Sulfur, phosphorous, and some radioactive elements such as halogens. Inorganic compounds will not have carbon. 


 Organic compounds are classified in different functional groups such as Alcohol, Ether, Aldehyde, Ketone, Amine, Nitro, that functional group of atom in molecule determines characteristics of molecule, how that molecule will behave, on the other side classification of the Inorganic molecules in so easy to remember and that classification fall in to some basic categories of acid, base, salts and metal. Organic Chemistry study about Structure, properties, synthesis of Carbon based compounds, organic chemistry focuses on Photochemistry, stereochemistry, hydrogenation, isomerization, fermentation and on the other hand Inorganic Chemistry explain about electrochemistry, crystallography, atomic structure, coordination of compounds, chemical bonding, acid-base reactions although organic and Inorganic chemistry studies different concept but people said both organic and inorganic chemistry always overlap. Organic Chemistry used in all over are such as Biotechnology, Chemicals, petroleum, pharmaceutical as well as inorganic chemistry also so much useful in industries like fabric and plastics, microchip, mining, ore, metals, paints, pigments, coatings.

                                         There is so much difference in between Organic, Inorganic and Analytical Chemistry, normally Organic substance will burn, Organic matter mostly found in living or once living, organism, Organic substances found in all biology in nature, Generally Inorganic matter is not present in living, Generally inorganic compounds less complex than organic compounds. Presence of carbon prevents organic molecule from forming salts. On the other hand, inorganic compounds form salts and easily soluble in water.

                                         Organic compounds react slowly than inorganic compounds and slower reaction speed allow the formation of more complex product in reaction. Organic compounds are fewer conductors of heat and electricity than inorganic compounds. Inorganic compounds have higher melting and boiling point than organic compounds. Generally ionic bonds forms in inorganic compounds and covalent bond always present in organic compounds, some examples of organic and inorganic compounds

      Organic compounds: - Urea, Methane, Gasoline

      Inorganic compounds: - Minerals, Metal Complex

Organic Chemistry cover a many areas including

  • Medicinal Chemistry - Medicinal chemistry studies and work related Design, Development, and synthesis of medicinal drugs, and its coordinates with pharmacology (Study of the drug action)
  • Organometallic chemistry - Although this is inorganic chemistry branch then is works like organic. This is Branch of Organic chemistry which deals with study of compounds containing bonds between carbon and meal.
  • Polymer chemistry - This Branch of organic chemistry study about the synthesis, and characterization of organic polymer.
  • Physical organic chemistry -this branch study about interrelationships between structure and reactivity in organic molecules.
  • Stereochemistry - Study about in this Branch is spatial arrangements and there effect on chemical and physical properties of organic compounds.

Inorganic chemistry study about properties and behavior of inorganic compounds and inorganic chemistry cover many area includes

  • Bioinorganic chemistry - This branch study about interaction of metal ions with living body, generally through their effect on enzyme activity.
  • Geochemistry - Study about chemical composition and change in mineral, rocks, and atmosphere of the earth
  • Nuclear chemistry - Study about radioactive substances.
  • Organometallic chemistry - This branch works in organic as well as inorganic chemistry, herein this branch works as a chemical compounds containing bonds between metal and a metal.
  • Solid-state chemistry- Study about synthesis, structure and properties of solid material chemistry.

Analytical chemistry Is the branch of chemistry which deals with study of qualitative and quantitative analysis of chemical compounds, and analytical chemistry covers many branches 


  • Forensic chemistry - This branch of analytical chemistry deals with study of chemical principles and techniques and how to analyses the crime.
  • Environmental chemistry - Study about the chemical and biochemical compounds that occur in environment.
  • Bioanalytical chemistry - This branch studies about the examination of biological material like urine, saliva, sweat, blood, hair and detect the what component resent in that and detects a specific drug on that.


Analytical chemistry is chemistry of analysis of organic and inorganic compounds weather that compound is correct or any impurity is there, analytical chemistry mostly organic scientists are using for the know that they made what they thought. There are so many analytical instrument using in organic and inorganic chemistry for analysis some name are coated here

  • Organic Elemental analyzer
  • XRD
  • Transmission Electron microscope
  • IR
  • NMR
  • Organic mass spectrometer
  • Chromatographic techniques.

Analytical chemistry uses instruments, methods to separate, analyze, identify, quantify the organic matters, in the separation and quantification may constitute the entire analyze or use combine method. Analytical chemistry consists of wet chemical method and modern instrumental techniques

                Classical qualitative methods is using for precipitation, distillation, extraction. Identification can do by differences in color, odor, boiling and melting points, reactivity or radioactivity, mass or volume changes quantify amount. Instrumental methods mainly using for separate sample using chromatography, electrophoresis, field flow fractionation.

Quantitative analysis divided in to two types 

(1)   Gravimetric analysis - This technique determines the amount of material present in the any sample

(2)   Volumetric analysis -Titration of reactant and solution being analyzed until some end point is reached. Best example for this analysis titration of acid- base.

This is the difference between organic, inorganic and analytical chemistry as per the study of basic chemistry, how all branches are different to each other but they all are overlap to each other for study.
