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 | 1. Rhodium |
| B. Blood pigment | 2. Cobalt |
| C. Wilkinson's catalyst | 3. Magnesium |
| D. Vitamin B12 | 4. Iron |
Codes
| Options: | A | B | C | D |
| 1. | 2 | 3 | 4 | 1 |
| 2. | 3 | 4 | 1 | 2 |
| 3. | 1 | 4 | 3 | 2 |
| 4. | 4 | 1 | 3 | 2 |
Hint: Blood pigment contains iron.
Central metal ions present on coordination compounds determine the properties of coordination compounds and their biological role.
