Match the coordination given in Column-I with the central metal atoms given in Column-II and assign the correct code.
|
Column-I (Coordination compound) |
Column-II (Central metal atom) |
||
| A. | Chlorophyll | (i) | Rhodium |
| B. | Blood pigment | (ii) | Cobalt |
| C. | Wilkinson's catalyst | (iii) | Magnesium |
| D. | Vitamin B12 | (iv) | Iron |
Codes:
| A | B | C | D | |
| 1. | (ii) | (iii) | (iv) | (i) |
| 2. | (iii) | (iv) | (i) | (ii) |
| 3. | (i) | (iv) | (iii) | (ii) |
| 4. | (iv) | (i) | (iii) | (ii) |
Hint: Blood pigment contains iron.
Central metal ions present on coordination compounds determine the properties of coordination compounds and their biological role.
|
Column l (Coordination compound) |
Column (Central metal atom) |
| A. Chlorophyll | 1. Magnesium |
| B. Blood pigment | 2. Iron |
| C. Wilkinson catalyst | 3. Rhodium |
| D. Vitamin B | 4. Cobalt |
Hence, the correct answer is the second option.
