  2. Ethylene oxide - Wikipedia

    en.wikipedia.org/wiki/Ethylene_oxide

    The reaction occurs easier with the last two acids: (CH 2 CH 2)O + HCl → HO–CH 2 CH 2 –Cl. The reaction with these acids competes with the acid-catalyzed hydration of ethylene oxide; therefore, there is always a by-product of ethylene glycol with an admixture of diethylene glycol. For a cleaner product, the reaction is conducted in the ...

  3. Standard enthalpy of formation - Wikipedia

    en.wikipedia.org/wiki/Standard_enthalpy_of_formation

    For many substances, the formation reaction may be considered as the sum of a number of simpler reactions, either real or fictitious. The enthalpy of reaction can then be analyzed by applying Hess' law, which states that the sum of the enthalpy changes for a number of individual reaction steps equals the enthalpy change of the overall reaction.

    The β-diketiminato aluminum(I) complex Al{HC(CMeNAr) 2} (Ar = 2,6-diisopropylphenyl), which bears an Al-based sp x lone pair, reacts with alkenes and alkynes to give alumina (III) cyclopropanes and alumina (III) cyclopropenes in a process analogous to the formation of π-complexes by transition metals.

  5. Ethylene - Wikipedia

    en.wikipedia.org/wiki/Ethylene

    Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

  6. Born–Haber cycle - Wikipedia

    en.wikipedia.org/wiki/Born–Haber_cycle

    The cycle is concerned with the formation of an ionic compound from the reaction of a metal (often a Group I or Group II element) with a halogen or other non-metallic element such as oxygen. Born–Haber cycles are used primarily as a means of calculating lattice energy (or more precisely enthalpy [note 1]), which cannot otherwise be measured ...
