When styrene (vinylbenzene) is commercially polymerized, about 1–3% of 1,4-divinylbenzene is often added to the styrene. The incorporation of some divinylbenzene gives a polymer with more strength and better resistance to organic solvents. Explain how a very small amount of divinylbenzene has a marked effect on the properties of the ...
WebMar 20, 2024 · The reactions that cycloalkanes can undergo are the same as for alkanes. Both burn in the presence of excess oxygen in typical combustion reactions to produce carbon dioxide and water. Likewise, both can undergo halogenations, in which a hydrogen is replaced by a halogen atom (F, Cl, Br, I). The simple and the bigger cycloalkanes are very stable, like alkanes, and their reactions, for example, radical chain reactions, are like alkanes. The small cycloalkanes – in particular, cyclopropane – have a lower stability due to Baeyer strain and ring strain. They react similarly to alkenes, though they do not react in electrophilic addition, but in nucleophilic aliphatic substitution. These reactions are ring-opening reactions or ring-cleav…
WebPreparation of Cycloalkanes; Following methods are commonly used for the preparation of cycloalkanes. (a) From dihalogen compounds : α-ω elimination from dihalides having halogen atoms on two ends of carbon chain (α-ω dihalides) with Na or Zn dust gives rise to the formation of cycloalkanes.The method can be regarded as intramolecular Wurtz … WebAnd for all hydrocarbons, you're gonna get CO2 and H2O as the products of a combustion reaction. Delta H zero for this reaction is negative 890 kiloJoules per one mole of methane which means one mole of methane, if you combust one mole of methane, you're gonna get 890 kiloJoules of heat. And so this is an exothermic reaction, heat is given off.
