Options
- A. 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
- B. 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 ]
- C. 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
- D. Set-I: [ Cr ( NH _3 )_5 Cl ] Cl _2 and [ Co ( en ) ( NH _3 )_2 Cl _2 ] Set-II: [ Cr ( H _2 O )_6 ] Cl _3 and [ Cr ( H _2 O )_5 Cl ] Cl _2 H _2 O
Answer
C. 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
Step-by-step solution
Set-I: \( [ Co ( NH _3 )_3 ( NO _2 )_3 ]\) and \( [ Co (e n)_2 Cl _2 ]\) Set-II: \( [ Co ( NH _3 )_5 Cl ] SO _4\) and \( [ Co ( NH _3 )_5 ( SO _4 ) ] Cl \) Set-I: Set-II: \( [ Co ( NH _3 )_5 Cl ] SO _4\) and \( [ Co ( NH _3 )_5 SO _4 ] Cl \) are ionisation isomers.
