\([en = H_2NCH_2CH_2NH_2] \)

(A) Set-I: \([Ni(CO)_4]\) and \([PdCl_2(PPh_3)_2]\)

Set-II: \([Co(NH_3)_5Cl]SO_4\) and \([Co(NH_3)_5(SO_4)]Cl\)

(B) Set-I: \([Co(en)(NH_3)_2Cl_2]\) and \([PdCl_2(PPh_3)_2]\)

Set-II: \([Co(NH_3)_6][Cr(CN)_6]\) and \([Cr(NH_3)_6][Co(CN)_6] \)

(C) Set-I: \([Co(NH_3)_3(NO_2)_3]\) and \([Co(en)_2Cl_2]\)

Set-II: \([Co(NH_3)_5Cl]SO_4\) and \([Co(NH_3)_5(SO_4)]Cl \)

(D) Set-I: \([Cr(NH_3)_5Cl]Cl_2\) and \([Co(en)(NH_3)_2Cl_2]\) 

Set-II: \([Cr(H_2O)_6]Cl_3\) and \([Cr(H_2O)5Cl]Cl_2.H_2O\)

Answer 1

(C) Set-I: \([Co(NH_3)_3(NO_2)_3]\) and \([Co(en)_2Cl_2]\) 

Set-II: \([Co(NH_3)_5Cl]SO_4\) and \([Co(NH_3)_5(SO_4)]Cl \)

Set-I:

Set-II:

\([Co(NH_3)_5Cl]SO_4\) and \([Co(NH_3)_5SO_4]Cl\) are ionisation isomers.
