why alkanes also known as parrafins?

Parrafin is just an older term.  Alkenes are also known as olefins.

C6H14\nAll alkanes follow the same formula:\nC(n)H(2n+2) where n is any real number.\nSo hexane, hex meaning 6, is 6 carbons, and 12+2 hydrogens, 14.

Saturated means that all the Carbon-Hydrogen bonds are 'single' bonds.  Thus, the previously double and triple bonded carbon-hydrogen atoms cannot not take anymore H atoms...they are saturated with them!\n\nStructure is very simple. They are pretty much straight floppy chains.  Think of a shoelace flopping around.\n\nSaturated hydrocarbons are in the 'ane' family of names.  Pentane, Octane, Butane, etc.\n\nProperties:  One great property is that they flop around a lot.  This makes them pass through tight spaces easier, and contribute to clogging far less than unsaturated hydrocarbons (double and triple bonds are rigid, and thus not floppy).  This floppyness is especially important for arteries.  Eat more unsaturated hydrocarbons (fats), get more clogged arteries.  Eat saturated (floppy), and they don't get stuck.\n\nUses:  One use is gasoline (Octane).  Straight-chain (saturated) burns more efficiently.\n\nHope this helps.

There is no such molecule as there are 3 families of simple hydrocarbons:\n1. the alkanes (Cn H2n+2) of which methane (CH4) is the first. This type of compound has all single bonds in a chain;\n2. the alkenes (Cn H2n) of which ethene (C2H4) is the first. This type of compound has one double bond; and\n3. the alkynes (CnH2n-2) of which acetylene (C2H2) is the first.  This type of compound has one triple bond.\n\nC2H3 fits none of these patterns. However it could be the empirical ('simpest') formula for C4H6 (butylene)

r u really serious !!! how can one find a pie bond in an alkane????

Pentane is a Highly Flammable Liquid which may form Explosive Mixtures with air.  It chemically combines with the oxygen in the atmosphere to give carbon dioxide and water:\n\nC5H12 (l) + 8O2 (g) --> 5CO2 (g) + 6H2O (g)

alkenes like ethene,propene undergo addition reactions at high temperatures and pressures to form addition polymers like polythene,PVC etc.\nalkenes like ethene are used in artificial ripening of fruits.

Loads of stuff. Oil is broken down in to many different substances, and stuff is made from them. Plastic, polyester, polythene, nylon etc. They use a bi-product to make roads. Plus lubricants, vaseline, industrial grease. I think you can get alcohols from it, ethanol, methanol etc. Different fuels come from it, diesel, aviation fuel, jet fuel, normal fuel. You'd be surprised.\nUuuh, and all the stuff he said up there too.

I think A and D are both true.  Because parafin is nonpolar, it should be soluble in a non-polar solvent.  Likewise, because ethanol is polar, it should be more soluble in a polar solvent that in a non-polar one.  Both of these go along with the idea that "like dissolves like".

Chlorofluorocarbons (CFC) are a group of simple alkanes (compounds of carbon and hydrogen) that also contain both chlorine and fluorine atoms.  They were widely used as propellant gases, dry cleaning solvents and refrigerants (Freon, and others).  As gases, these compounds often rise into the upper layers of the atmosphere where they react with sunlight to break down, releasing chlorine and fluorine atoms.  This process is called photodissociation.\nFree halogen atoms (such as chlorine and fluorine) react readily with ozone.  Their use over the last several decade has lead to a depletion in the ozone layer which protects our atmosphere from harmful UV radiation.  The international agreement called the Montreal Protocol is the reason that their use is prohibited.

Because if it is made of plastic, Plastic is a product of petroleum.\n\nYou will probably be surprised to know that a plastic bottle is made from the same petrochemical as the fiber we call polyester!\n\nAll plastic products, many of the materials used to make the clothes you wear, or the carpet you walk on, plus hundreds of the other products we take for granted, are made from petrochemicals. As the name implies, a main ingredient in petrochemicals is oil. \n\nPlastic: Any of various complex organic compounds produced by polymerization, capable of being molded, extruded, cast into various shapes and films, or drawn into filaments used as textile fibers. \n-- Webster's Dictionary\n\nThat's an interesting definition, you may be thinking, but really -- how is plastic made? What's involved in the plastics manufacturing process? \nThe Basics of Plastic Manufacturing \n\nThe term "plastics" encompasses organic materials, such as the elements carbon (C), hydrogen (H), nitrogen (N), chlorine (Cl) and sulfur (S), which have properties similar to those naturally grown in organic materials such as wood, horn and rosin. Organic materials are based on polymers, which are produced by the conversion of natural products or by syththesis from primary chemicals coming from oil, natural gas or coal. \n\nThe plastic manufacturing process begins by heating the hydrocarbons in a "cracking process." Here, in the presence of a catalyst, larger molecules are broken down into smaller ones such as ethylene (ethene) C2H4, propylene (propene) C3H6, and butene C4H8 and other hydrocarbons. The yield of ethylene is controlled by the cracking temperature and is more than 30% at 850°C and such products as styrene and vinylchloride can be produced in subsequent reactions. These are then the starting materials for several other types of plastics. Therefore, this process results in the conversion of the natural gas or crude oil components into monomers such as ethylene, propylene, butene and styrene. \n\nThese monomers are then chemically bonded into chains called polymers. Different combinations of monomers yield plastic resins with different properties and characteristics. Each monomer yields a plastic resin with different properties and characteristics. Combinations of monomers produce copolymers with further property variations. \n\nThe resulting resins may be molded or formed to produce several different kinds of plastic products with application in many major markets. The variability of resin permits a compound to be tailored to a specific design or performance requirement. This is why certain plastics are best suited for some applications while others are best suited for entirely different applications. For instance, impact strength measures the ability of a material to withstand shock loading. Heat resistance protects the resin from exposure to excessive temperatures. Chemical resistance protects the resin from breakdown due to exposure to environmental chemicals. \n\nSome examples of material properties in plastic product applications are: \n\nHot-filled packaging used for products such as ketchup \nChemical-resistant packaging used for products such as bleach \nImpact strength of car bumpers \n\nThe Structure of Polymers \n\nPolymers are created by the chemical bonding of many identical or related basic units and those produced from a single monomer type are called homopolymers. These polymers are specifically made of small units bonded into long chains. Carbon makes up the backbone of the molecule and hydrogen atoms are bonded along the carbon backbone. \n\nPolymers that contain primarily carbon and hydrogen are classified as organic polymers. Polypropylene, polybutylene, polystyrene and polymethylpentene are examples of these.\n\nEven though the basic makeup of many polymers is carbon and hydrogen, other elements can also be involved. Oxygen, chlorine, fluorine, nitrogen, silicon, phosphorous and sulfur are other elem

Some countries still use "Petrol station". Gas is colloquial usage. \nGas is derived from the word Gasoline, which is another name for petroleum.
