- Explain why free-radical halogenation usually gives mixtures of productsarrow_forwardThe standard enthalpies of formation of ClO and ClO2 are101 and 102 kJ/mol, respectively., Calculate the overallenthalpy change for each step in the following catalyticcycle: What is the enthalpy change for the overall reaction thatresults from these two steps? ClO(g) + O3(g) ---->ClO2(g) + O2(g) ClO2(g) + O(g) ---->ClO(g) + O2(g)arrow_forwardSuggest conditions for performing the following reaction:arrow_forward
- What is the increasing order of reactivity ?arrow_forwardConsider the fluorination and bromination of methane by the free radical mechanism.Making use of bond energies discuss the thermodynamic favorability (free energy change) of the two reactions.arrow_forward10. The following reaction has variation of free energy value of AG = -2.1 kJ/mol CH;Br + H2S 2 CH;SH + HBr (a) Calculate Keq at room temperature (25°C) for this reaction as written. (b) Starting with a 1 M solution of CH3B and H2S, calculate the final concentrations of all four species at equilibrium.arrow_forward
- Acetic acid is weak acid but it gives strongly acidic solution when dissolved in perchloric acid. Explain.arrow_forwardProvide the structure of the product and write the mechanism of its formation for the following reactions: And explain in details on what actually happens. (g) H,SO. ? (h) NANO, HCI ? NH,arrow_forwardDerive as many compound refrigerant from ethane replacing hydrogen atoms by halogen elements (chlorine, flourine and bromine)arrow_forward
- write the complete reaction mechanism between ethylbromide (using steps and arrows ) and NaOH and determine the type of this reaction?arrow_forwardExplain why bromination is more selective than chlorination in replacing the 3o hydrogen. Use sentences; drawings; and structures in the answer. Include Hammond postulates and discuss transition state energies and thermodynamics in the rate-determining step of the reaction.arrow_forwardGive typed explanation Which diagram shows the Gibbs free energy as a function of reaction progress for the following reaction?arrow_forward
