The correct statement(s) regarding the binary transition metal carbonyl compounds is (are) (Atomic numbers : )
Options:(select one or more)
Answer:
B, C
Solution:
CO is a strong-field ligand, so metal carbonyls are generally low-spin complexes. Fe(CO)₅ and Ni(CO)₄ both obey the 18-electron rule, not 16-electron rule, making (A) incorrect. Lower oxidation state of the metal increases π-back bonding and strengthens the M–C bond, so (C) is correct. Increasing oxidation state decreases back bonding and strengthens the C–O bond; hence (D) is false.
