Question
Which of the following complexes will exhibit maximum attraction to an applied magnetic field? (A) [Zn(H2O)6]2+ (B) [Co(en)3]3+ (C) [Co(H2O)6]2+ (D) [Ni(H2O)6]2+
Answer: C
💡 Solution & Explanation
Complex Electronic configuration No. of unpaired electrons [Co(en)6]3+ Co3+: 3d6 , g ,2 ,2 g e , t [Co(H2O)6]2+ Co2+: 3d7 1,1 g 1,2 ,2 g e , t [Ni(H2O)6]2+ Ni2+:3d8 1,1 g ,2 ,2 g e , t [Zn(H2O)6]2+ Zn2+ : 3d10 ,2 g ,2 ,2 g e , t Greater the number of unpaired electrons greater is the interaction in magnetic field. | JEE(Main) 2023 | DATE : 13-04-2023 (SHIFT-2) | PAPER-1 | CHEMISTRY PAGE # 4
