WebThe process of cracking is endothermic, as the bonds formed are weaker than the bonds that are broken. Cracking relies on high temperatures to drive the process forward, and … Alkanes and alkenes both form homologous series of hydrocarbons, but: 1. alkanes are saturated, their carbon atoms are only joined by C-C single bonds 2. alkenes are unsaturated, they contain at least one C=C double bond As a result, alkenes are more reactivethan alkanes. Alkenes can take part in reactions that … See more Cracking is important for two main reasons: 1. It helps to match the supply of fractionswith the demand for them. 2. It produces alkenes, which are useful as feedstockfor the petrochemicalindustry. See more The supply is how much of a fraction an oil refinery produces. The demand is how much of a fraction customers want to buy. Very often, fractional … See more
