... - Addition of HX to alkenes is regioselective and follows Markovnikov's rule: with unsymmetrical alkenes, the proton adds to the less substituted carbon of the double bond. Changes in mechanism lead to exceptions from Markovnikov's rule; for example, the peroxide initiated addition of HX to alkenes ...

Catalytic Functionalization of Methyl Group on Silicon: Iridium
... a carbon analogue of chlorotrimethlsilane (3b), did not give the desired borylation product at all, indicating that a silicon atom is essential for the C−H borylation (entry 1). As Et3SiCl (8) resulted in no reaction (entry 2), the C−H borylation takes place selectively at the methyl group on the si ...

Cracking (chemistry)
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 such as light hydrocarbons, by the breaking of carbon-carbon bonds in the precursors. The rate of cracking and the end products are strongly dependent on the temperature and presence of catalysts. Cracking is the breakdown of a large alkane into smaller, more useful alkanes and alkenes. Simply put, hydrocarbon cracking is the process of breaking a long-chain of hydrocarbons into short ones. More loosely, outside the field of petroleum chemistry, the term ""cracking"" is used to describe any type of splitting of molecules under the influence of heat, catalysts and solvents, such as in processes of destructive distillation or pyrolysis. Fluid catalytic cracking produces a high yield of petrol and LPG, while hydrocracking is a major source of jet fuel, Diesel fuel, naphtha, and again yields LPG.
