Web31 jul. 2024 · Thermodynamics of Solvation of Ions and Its Importance. Some idea of the importance of solvation can be gained from the calculated Δ H for the following process: (11.8.1) Na + ( g) + Cl − ( g) → Na + ( aq) + Cl − ( aq) with D e l t a H o = − 187 k c a l. The solvation energies of ions are so large that relatively small differences for ... WebDespite being less stable than an alkene, an alkyne is less reactive than an alkene, since reactivity depends on ΔG ‡ , which depends not only on the stability of the reactant but also on the stability of the transition state. When a proton adds to an alkene, an alkyl cation is formed. When a proton adds to an alkyne, a vinylic cation is formed. hurricane katrina recovery phaseWebAlkenes are relatively stable compounds, but are more reactive than alkanes because of the reactivity of the carbon–carbon π-bond.
