Cracking is a form of thermal decomposition, which breaks long chain hydrocarbons, many of which are not very useful, into shorter molecules by heating them. Many of the substances with longer molecules produced from the fractional distillation of crude oil are cracked; for example, naphtha is cracked to produce gasoline. The cracking reaction is an example of a thermal decomposition, that is, breaking a molecules down with heat, by heating them to high temperature. The high temperature and catalyst are needed to facilitate the cracking reaction because you have to break the very strong carbon-carbon covalent bonds in the alkane molecule.
To subject to the process of cracking, as in the distillation of petroleum. To open and drink (a bottle of wine, liquor, beer, etc.). Sometimes a catalyst is added to lower the amount of heat needed for the reaction. Cracking is used especially for breaking petroleum molecules into shorter molecules and to extract low.
Apart from alkenes and alkanes what else is made during the process of cracking? Are larger hydrocarbons more or less flammable than smaller hydrocarbons?
In chemistry terms, cracking is a process in which complicated organicmolecules (such as kerogens or heavy hydrocarbons) are broken down into simpler molecules (e.g. light hydrocarbons) by breaking their carbon-carbon bonds. How fast the cracking process is and how long it takes for the end products to form are very dependent on the temperature and any existing catalysts. Cracking, also referred to as pyrolysis, is the breakdown of a large alkane into smaller, more useful alkanes and an alkene.
With a convenient surface for the cracking to take place. For example, decane (an alkane with 10 carbons) can be cracked to produce octane and ethene. Decane octane + ethene. C 10 H 22 (g) C 8 H 18 (g) + C 2 H 4 (g) Octane is used as petrol. Ethene is used in the manufacture of polymers. Best Answer: In petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules (e.g. Light hydrocarbons) by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on.
Cracking is used in petroleum to form 'light' products such as LPG and gasoline.
