Consider the following conversions: (i) O_((g))+e^(-) to O_((g))^(-),

1.	Consider the following conversions: (i) O_((g))+e^(-) to O_((g))^(-),DeltaH_(1) (ii) F_((g))+e^(-) to F_((g))^(-),DeltaH_(2) (iii) Cl_((g))+e^(-) to Cl_((g))^(-),DeltaH_(3) (iv) O_((g))^(-) +e^(-) to O_((g))^(2-),DeltaH_(4) the according to given information the incorrect statement is :
Answer» `DeltaH_(3)` is more negative than `DeltaH_(1) and DeltaH_(2)` `DeltaH_(1)` is LESS negative than `DeltaH_(2)` `DeltaH_(1),DeltaH_(2) and DeltaH_(3)` are negative whereas `DeltaH_(4)` is POSITIVE `DeltaH_(1) and DeltaH_(3)` are negative whereas `DeltaH_(2) and DeltaH_(4)` positive Solution :order of ELECTRON gain enthalpy: `Cl gt F gt O` Second electron gain enthalpy for an element is always positive.
