what is meaning of organic, physical and inorganic chemistry?

Question

chemistry

Answer 1

Physical chemistry has to do with the physics of chemistry, such as the parts and structure of atoms and how they bond together to form molecules.

Organic chemistry is related to carbon and all there many different carbon based compounds.

Inorganic chemistry deals with non-carbon based compounds.

Answer 2

They broke up the study of chemistry into these sub-categories (actually, quite a few more, depending on what you want to study) so that it's in easier-to-digest chunks. Organic chemistry deals specifically with chemicals that have a carbon backbone, and is closely (though not exclusively) linked to studies of substances related to biological systems (a lot of crossover with biochemistry, in other words). Inorganic chemistry, as the name implies, deals with everything else: those substances without a carbon structure to it (carbon can still appear in it, but it isn't the main structural component... so CO2, Ca(CO3)2 etc are inorganic, as well as salts, metals and many acids and bases. Physical chemistry sort of falls in a side category, and deals with exactly HOW chemical reactions occur, studing atomic bonds, energy transfer, and kinetics... sort of that gray area where chemistry and physics intersect.

Answer 3

Organic chemistry is the study of hydrocarbons - things that contain Carbon combined with other elements as well.

Inorganic chemistry basically is the study of the properties and behavior of compounds that aren't hydrocarbons.

Physical chemistry - According to renowned chemist Gilbert Lewis "Physical chemistry is anything interesting." As a combined science of physics, chemistry, thermodynamics, electrochemistry, and quantum mechanics it functions to provide molecular-level interpretations of observed macroscopic phenomena. Typically, changes in temperature, pressure, volume, heat, and work of systems in the solid, liquid, and or gas phase are correlated to microscopic atomic and molecular interactions.

The type of relationships that physical chemistry tries to resolve include:

The effects of intermolecular forces on the physical properties of materials (plasticity, tensile strength, surface tension in liquids)
The effects of molecular kinetics on the rate of a reaction
How the identity of ions affects electrical conductivity of materials
Most cite Willard Gibbs as the founder of physical chemistry as stemming from his 1876 paper: “On the Equilibrium of Heterogeneous Substances”, wherein such cornerstones as free energy, chemical potential, and phase rule were developed.

Modern physical chemistry is firmly grounded upon physics. Important areas of study include thermochemistry (chemical thermodynamics), chemical kinetics, quantum chemistry, statistical mechanics, electrochemistry, surface and solid state chemistry, and spectroscopy. Physical chemistry is also fundamental to modern materials science.

--- I havent had any physical chemistry yet. It sounds kinda scary lol. Hope this helped!
