![]() Notice that the names of the substituent groups are in alphabetical order.Īlkane being saturated compounds can undergo only substitution reactions. If the two substituents are identical, the numbers are both written before the substituent name, and the prefix di is added to the name. If two substituents are on the same carbon of the parent chain, the number of the carbon they are attached to is written before each substituent name. The name(s) of the substituent group(s) and the location number(s) precede the parent name. The various components of crude oil have different sizes, weights and boiling temperatures so, the first step is to separate these components.īecause they have different boiling temperatures, they can be separated easily by a process called fractional distillation.Ī substituent group is any atom or group that has replaced a hydrogen atom on the parent chain. ![]() Methane is the major constituent of the natural gas and occurs along with petroleum in the earths sedimentary traps.Īnaerobic decomposition of organic matter, in the presence of bacteria, liberates methane.įor example, bio-gas produced by anaerobic decomposition of animal dung, excreta and plant wastes is rich in methane gas. ![]() The natural wax found near petroleum wells is a mixture of higher solid hydrocarbons. It usually contains alkanes having up to forty carbon atoms in their molecule. ![]() Petroleum and natural gas are largely mixtures of different alkanes.Īn alkyl group is a group of carbon and hydrogen atoms attached to an alkane molecule. This solid was an addition polymerGive the name of the addition polymer that formed inside the cylinder.ĭraw the structure of the monomer, tetrafluoroethene, from which it is formed.Ī decane molecule is split into two smaller molecules.Complete the equation by adding the formula of the other product. No gas came out He cut the cylinder open and found that the gas had changed into a white solid. The double bondmakes them quite reactive and they are used as a starting material tomake many other organic compounds.Ĭompound A has fewer C atoms or Compound B has fewer H atoms Compound A is reactive Compound A has C Cdouble bond or can be used to make or Compound A is unsaturated many substancesWhy is compound A useful in industry or can be used in polymerisationmaking plasticsnamed plastic or can be used as a fuel. ![]() Decane Ing Equation Free Radical Reaction. ![]()
