Consider the following conversions : (i) O(g)+e−⟶O(g)−,ΔH1\text{O}_{(g)} + e^- \longrightarrow \text{O}^-_{(g)}, \Delta H_1 (ii) F(g)+e−⟶F(g)−,ΔH2\text{F}_{(g)} + e^- \longrightarrow \text{F}^-_{(g)}, \Delta H_2 (iii) Cl(g)+e−⟶Cl(g)−,ΔH3\text{Cl}_{(g)} + e^- \longrightarrow \text{Cl}^-_{(g)}, \Delta H_3 (iv) O(g)−+e−⟶O(g)2−,ΔH4\text{O}^-_{(g)} + e^- \longrightarrow \text{O}^{2-}_{(g)}, \Delta H_4 That according to given information the incorrect statement is : a. ΔH3\Delta H_3 is more negative than ΔH1\Delta H_1 and ΔH2\Delta H_2 b. ΔH1\Delta H_1 is less negative than ΔH2\Delta H_2 c. ΔH1,ΔH2\Delta H_1, \Delta H_2 and ΔH3\Delta H_3 are negative whereas ΔH4\Delta H_4 is positive d. ΔH1\Delta H_1 and ΔH3\Delta H_3 are negative whereas ΔH2\Delta H_2 and ΔH4\Delta H_4 are positive
