Which of the following statements is INCORRECT about the given processes? O(g) + e⁻ → O⁻(g) Process-1 O⁻(g) + e⁻ → O²⁻(g) Process-2 N(g) + e⁻ → N⁻(g) Process-3 N⁻(g) + e⁻ → N²⁻(g) Process-4
Options:
Answer:
D
Solution:
Process 1, O(g) + e⁻ → O⁻(g), is exothermic. Process 2 is endothermic because a second electron is added to an anion. Process 3 is endothermic because nitrogen has a stable half-filled 2p³ configuration. Process 4 is also endothermic and has a greater magnitude than process 3. Therefore, three processes are endothermic; A, B, and C are correct. D is the incorrect statement, so the answer is D.
