Consider the following ionisation reactions : I.E. (kJ mol-1) A(g) -> A+(g) + e-, A1; B+(g) -> B2+(g — Periodic Table and Periodicity Chemistry Question
Question
Consider the following ionisation reactions : I.E. (kJ mol-1) A(g) -> A+(g) + e-, A1; B+(g) -> B2+(g) + e-, B2; C+(g) -> C2+(g) + e-, C2. I.E. (kJ mol-1) B(g) -> B+(g) + e-, B1; C(g) -> C+(g) + e-, C1; C2+(g) -> C3+(g) + e-, C3. If monovalent positive ion of A, divalent positive ion of B and trivalent positive ion of C have zero electron. Then incorrect order of corresponding I.E. is :
Answer: D
💡 Solution & Explanation
A => H(1s1), B => He(1s2), C => Li(1s2 2s1). Evaluate based on IE of H, He, Li and their corresponding ions.
