Introduction: chemistry plays a major role in science and its aspect. Synthetic molecules have a central role in chemistry and its scientific factors, as it helps us go deeply into chemistry’s phases and gives a better understanding of the concept according to the chosen task or topic discussed. Thus it’s very essential to know and understand the importance of synthetic molecules and how does it affect our daily lives or the community we are surrounded by. It can affect our moral, ethical, economic, cultural, and environmental factors. This essay will focus on exploring synthetic molecules in (nylon) and their impact on technology and our daily lives.
Body 1: synthetic chemistry is using complex compounds to form simpler substances by

To start off nylon is durable (last long) because it contains molecules that have a large number of amide functions. From these functions it will form a bond (s-N-H+s) this leads to H bonding with the chains, even though H has a weak intermolecular interaction they have high numbers that will lead to strong bonding chains that will increase strength and durability. Nylon generally costs low as it’s a man-made synthetic not a natural fabric that must be collected or farmed by animals thus it will cost less. Furthermore nylon has some positive impacts on the environment because they can be recycled that can turn into new nylon productions so that’s why we need to increase the accessibilities of nylon and their recycling schemes. Moreover nylon has good resistance to chemicals, as well it has a high voltage and its used for electric-components thus it’s filled with variety of materials to enhance weathering, impact on resistance and stiffness. In addition nylon repels and resists damage from oil and many other chemicals. As nylon is light weighted, it resists wrinkles, easy to wash, it has strength and it fast for drying. As for nylon advantages in the technology factor its used for new body car parts, parachutes to inexpensive machine and

rapid development of polymer chemistry after World War II a host of new synthetic fibers
The available material for the propellers in the market consists of three main choices: nylon, plastic and carbon fiber.
Making nylon 6,6 is even easier if you use a diamine and a diacid chloride instead of a diacid. This is because acid chlorides are much more reactive than acids. The reaction is done in a two-phase system. The amine is dissolved in water, and the diacid chloride in an organic solvent. The two solutions are placed in the same beaker. Of course, the two solutions are immiscible, so there will be two phases in the beaker. At the interface of the two phases, the diacid chloride and diamine can meet each other, and will polymerize there. There is special way to do this called the "Nylon Rope Trick"4, and we'll show you how to do that in just a minuteMaking nylon 6,6 is even easier if you use a diamine and a diacid chloride instead of a diacid. This is because acid chlorides are much
This chemistry book report is focus on a book called “Napoleon's buttons: How 17 molecules changed history” by Penny Le Couteur and Jay Burreson. The publisher of this book is Tarcher Putnam, the book was published in Canada on 2003 with 17 chapters (hey the number match the title of the book!) and a total of 378 pages. The genre of this book is nonfiction. “Napoleon's Buttons” contain a fascinating story of seventeen groups of molecules that have greatly changed the course of history and continuing affect the world we live in today. It also reveal the astonishing chemical connection among some unrelated events, for example: Chemistry caused New Amsterdamers to be renamed New Yorkers and one little accident of detonating cotton apron in a minor housekeeping mishap lead to the development of modern explosives and the founding of the movie industry.
spaced –CONH– amide groups. Nylon 6-6, or poly(hexamethylneadipamide), is composed of. two structural monomers (hexamethylendiamine (H2N(CH2)6NH2) and adipic acid. (HOOC(CH2)4COOH), whereas Nylon 6, or poly(6-caprolactam), is composed of a single structural unit (either 6-aminocaproic acid (H2N(CH2)4COOH) or caprolactam). Ultimately, the answer is yes.
In this experiment we produced a Nylon-6,10 polymer from a reaction with a sebacoyl chloride (decanedioyl dichloride)/dichloromethane mixture and a mixture of water, 1,6-hexanediamine and sodium carbonate. The name ‘Nylon-6,10’ indicates that the diamine that it was made from has 6 carbons and the diacid it was made from has 10 carbons. The sodium carbonate was used in the preparation of Nylon-6,10 because it is a strong base that will lower the acidity of the solution and neutralize the hydrochloric acid that was produced as a by-product. The HCl was produced as a by-product instead of water because we used milder conditions by substituting decanedioyl dichloride for decanedioic acid. The decanedioyl dichloride is a better alternative because it is more reactive towards the
Esters are pervasive in nature and commonly used in industry which makes them an essential functional group to everyday life. This investigation was conducted to find how the molecular structure and electron movement contribute to the properties performed by esters within molecules. It was found that, in nature, esters are responsible for pheromones released by plants and animals and also for the pleasant aromas of many fruits and flowers. In industry, it was found that esters are needed to create plexiglas (please define this and the following terms as footnotes), dacron , polyethylene , terephthalate , benzocaine , and procaine . Esters positively impact our world by contributing to the creation of polyester clothing which decreases our reliance on plantation grown material which could deplete the land, but also negatively affect our world due to the production of phthalic acid which is used in detergents and plastics that make the material toxic and damaging to the environment and those who use material with the acid.

This new invention had many better qualities and/or abilities than any other material in use already. Nylons are mostly known for their abilities to be dyed, to be unharmed by many kinds of household cleaning products or greases and oils, its rapid drying time, and above all, its silk-like appearance (The World Book). Nylons¡¯ tensile strength is greater than that of cottons, rayon, silk, and wool (Encarta). They also have characteristics that include elasticity, easy to clean,...
The production of synthetic detergents are an example of a standard chemical approach. If a useful substance has some undesirable properties an attempt is made to make a near copy synthetically which will perform better.
Oils, balls, swabs, bandages, tissue, paper, napkins, diapers, socks, underwear, shirts, shorts, sweaters, pants, coats, towels, linen, cushions, drapery, upholstery, rugs, carpet, comforters, mattresses, insulation, filtration, and many other things that are used daily by everyone are composed of, or inspired by cotton. Cotton is a soft, fluffy, naturally occurring fiber plant that can be processed into an array of materials and goods.

Synthetic plastics are used widely in food packaging, detergents, cosmetics, pharmaceuticals and other chemicals’ packaging. Almost 30% of the synthetic plastics are used for packaging applications in the world and this rate is expanding at 12% per annum. They have replaced traditionally used papers and cellulose products for packaging purposes because of owing better physical and chemical properties. Polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyurethane, poly(ethylene terephthalate), poly(butylene terephthalate) and nylon are most commonly used plastics. Plastics possess not only suitable thermal and mechanical properties but also better stability and durability. Plastics have attractive more public and media attention because of its durability and visibility in a litter as compared to other solid components. In 1993, total world consumption of this material was 107 million tons and it reached to 146 million tons in
