The correct statements about metal carbonyls are
A. The metal-carbon bonds in metal carbonyls possess both \(\sigma\) and \(\pi\)-character.
B. Due to synergic bonding interactions between metal and CO ligand, the metal-carbon bond becomes weak.
C. The metal-carbon \(\sigma\) bond is formed by the donation of lone pair of electrons on the carbonyl carbon into a vacant orbital of metal.
D. The metal-carbon \(\pi\) bond is formed by the donation of electrons from filled d-orbital of metal into vacant \(\pi^*\) orbital of CO.
Choose the correct answer from the options given below:
- A A and B Only
- B A, C and D Only
- C B and C Only
- D A and D Only
Answer & Solution
Correct Answer
(B) A, C and D Only
Step-by-step Solution
Detailed explanation
Statement A is correct. The metal-carbon bond in metal carbonyls possesses both \(\sigma\) and \(\pi\) character due to synergic bonding. Statement B is incorrect. The synergic bonding interaction between the metal and the CO ligand strengthens the metal-carbon bond. Statement C…
