Among the following options, select the option in which each complex in Set-I shows geometrical isomerism and the two complexes in Set-II are ionization isomers of each other. [en = H 2 NCH 2 CH 2 NH 2 ]

  1. Set-I: [Ni(CO) 4 ] and [PdCl 2 (PPh 3 ) 2 ] Set-II: [Co(NH 3 ) 5 Cl] SO 4 and [Co(NH 3 ) 5 (SO 4 )]Cl
  2. Set-I: [Co(en) (NH 3 ) 2 Cl 2 ] and [PdCl 2 (PPh 3 ) 2 ] Set-II: [Co(NH 3 ) 6 ][Cr(CN) 6 ] and [Cr(NH 3 ) 6 ][Co(CN) 6 ]
  3. Set-I: [Co(NH 3 ) 3 (NO 2 ) 3 ] and [Co(en) 2 Cl 2 ] Set-II: [Co(NH 3 ) 5 Cl]SO 4 and [Co(NH 3 ) 5 (SO 4 )]Cl
  4. Set-I: [Cr(NH 3 ) 5 Cl] Cl 2 and [Co(en) (NH 3 ) 2 C1 2 ] Set-II: [Cr(H 2 O) 6 ]Cl 3 and [Cr(H 2 O) 5 Cl]Cl 2 ·H 2 O

Correct answer: Set-I: [Co(NH 3 ) 3 (NO 2 ) 3 ] and [Co(en) 2 Cl 2 ] Set-II: [Co(NH 3 ) 5 Cl]SO 4 and [Co(NH 3 ) 5 (SO 4 )]Cl
