Question

For the following reactions, the metal complexes X and Y are
(i) $Ni\left(s\right)\underset{1atm,25C}{\overset{CO\left(g\right)}{\to }}X$
(ii) $FeC{1}_2\stackrel{2Na{C}_5{H}_5}{\to }Y$
X and Y are respectively

• A. $\left[Ni\right(CO{)}_4],[Fe\left(n^5{C}_5{H}_5{)}_2\right]$
• B. $\left[Ni\right(CO{)}_4],[Fe\left(n^1{C}_5{H}_5{)}_2\right]$
• C. $\left[Ni\right(CO{)}_5],[Fe\left(n^5{C}_3{H}_5\right)]$
• D. $\left[Ni\right(CO{)}_6],[Fe\left(n^1{C}_5{H}_5\right)]$

Answer 1

The correct option is A $\left[Ni\right(CO{)}_4],[Fe\left(n^5{C}_5{H}_5{)}_2\right]$

$\left[Ni\right(CO{)}_4],[Fe\left(n^5{C}_5{H}_5{)}_2\right]$
