The name organic chemistry came from the word organism. Prior to The name organic chemistry came from the word organism. Prior to 1828, all organic compounds had been obtained from organisms or their 1828, all organic compounds had been obtained from organisms or their remains. The scientific philosophy back then was that the synthesis of remains. The scientific philosophy back then was that the synthesis of organic compounds could only be produced within living matter while organic compounds could only be produced within living matter while inorganic compounds were synthesized from non-living matter. A theory inorganic compounds were synthesized from non-living matter. A theory known as "Vitalism" stated that a "vital force" from living organisms was known as "Vitalism" stated that a "vital force" from living organisms was necessary to make an organic compound. 1828, a German chemist necessary to make an organic compound. 1828, a German chemist Friedrich Wöhler (1800-1882) amazed the science community by using Friedrich Wöhler (1800-1882) amazed the science community by using the inorganic compound ammonium cyanate, NHthe inorganic compound ammonium cyanate, NH44OCN to synthesize OCN to synthesize

There are more carbon compounds than there are There are more carbon compounds than there are compounds of all other elements combined. Plastics, foods, compounds of all other elements combined. Plastics, foods, textiles, and many other common substances contain textiles, and many other common substances contain carbon. With oxygen and a metallic element, carbon forms carbon. With oxygen and a metallic element, carbon forms many important carbonates, such as calcium carbonate many important carbonates, such as calcium carbonate (limestone) and sodium carbonate (soda). Certain active (limestone) and sodium carbonate (soda). Certain active metals react with it to make industrially important carbides, metals react with it to make industrially important carbides, such as silicon carbide, an abrasive known as carborundum, such as silicon carbide, an abrasive known as carborundum, and tungsten carbide, an extremely hard substance used for and tungsten carbide, an extremely hard substance used for rock drills and metalworking tools.rock drills and metalworking tools.

A monomer (from Greek mono "one" and meros "part") is a small molecule that may
become chemically bonded to other monomers to form a polymer [1].
A single molecule that has the ability to combine with identical or similar molecules, a
process also known as polymerization.
Polymerization is a chemical reaction in which two or more molecules, or monomers, combine to form larger
molecules, or polymers.

Teflon, a product advertised as making life easy, is also used in a different form to keep stains off carpets and clothing. DuPont calls these products the housewives'
best friend. Teflon and the chemicals used in its production have grown into a $2 billion-a-year industry.
This includes ammonium perfluorooctanoate, known as C-8, which has been linked to cancer, organ damage and
other health effects in tests on laboratory animals.
In two to five minutes on a conventional stovetop, cookware coated with Teflon and other non-stick surfaces can exceed temperatures at which the
coating breaks apart and emits toxic particles and gases linked to hundreds, perhaps thousands, of pet
bird deaths and an unknown number of human illnesses each year, according to tests commissioned
by Environmental Working Group (EWG).
Proteins are large organic compounds made of amino acids arranged in a linear chain
and joined together by peptide bonds between the carboxyl and amino groups of
adjacent amino acid residues.
Proteins are probably the most important class of biochemical molecules, although of
course lipids and carbohydrates are also essential for life. Proteins are the basis for the
major structural components of animal and human tissue.

Biodegradable waste is a type of waste, typically originating from plant or animal sources, which may
be broken down by other living organisms. Waste that cannot be broken down by other living organisms may
be called non-biodegradable.
Biodegradable waste can be commonly found in municipal solid waste (sometimes called
biodegradable municipal waste, or BMW) as green waste, food waste, paper waste, and biodegradable plastics. Other biodegradable wastes include human
waste, manure, sewage, slaughterhouse waste.

This is a list for "non biodegrdable materials" .... * Plastic
Plastic is made from petrol, and petrol can not degrade in the nature very easily.
* Nylon Nylon is made from plastic also.
* Tin cans Tin cans are very bad for the nature.
NylonNylonNylon is a generic designation for a family of synthetic
polymers known generically as polyamides and first produced on February 28, 1935 by Wallace Carothers at DuPont. Nylon is one of the most commonly used
polymers.
