COORDINATION COMPOUNDS
28765
Which of the following is a \(\pi \)- complex
1 Trimethyl aluminium
2 Ferrocene
3 Diethyl zinc
4 Nickel carbonyl
Explanation:
(b)The complexes, in which, the metal and ligand form a bond that involves the \(\pi - \)electrons of the ligand are know as \(\pi - \)complexes e.g. Ferrocene \(Fe\)\({({\eta ^5} - {C_5}{H_5})_2},\) zeise’s salt \(K[PtC{l_3}({\eta ^2} - {C_2}{H_4})]\).
COORDINATION COMPOUNDS
28766
Which of the following is a \(\pi - \)acid ligand
1 \(N{H_3}\)
2 \(CO\)
3 \({F^ - }\)
4 Ethylene diamine
Explanation:
(b)\(CO \) has strong \(M \to L\) \(\pi - \)bonding ability so it can accept electron pairs from metal ion so it is a \(\pi \)-acid ligand.
