-Fe-CO-4-2-x2212- has longest C-x2212-O bond length- Since in the complex metal atom -xA0-is carrying maximum negative charge-xA0-therefore it would show maximum-xA0-synergistic-xA0-bonding-xA0-due to which C-x2013-O bond length would be-xA0-maximum-

Which of the following has longest $C - O$ bond length? (Free C-O bond length in $C O$ is $1.128 \circ A$ .)
$N i (C O)_{4}$
$[C o (C O)_{4}]^{⊖}$
$[F e (C O)_{4}]^{2 -}$
$[M n (C O)_{6}]^{+}$

$[F e (C O)_{4}]^{2 -}$ has longest $C - O$ bond length. Since in the complex metal atom is carrying maximum negative charge therefore it would show maximum synergistic bonding due to which $C - O$ bond length would be maximum.

Which of the following has longest C−O bond length? (Free C-O bond length in CO is 1.128∘A.)Ni(CO)4[Co(CO)4]⊖[Fe(CO)4]2−[Mn(CO)6]+

[Fe(CO)4]2− has longest C−O bond length. Since in the complex metal atom is carrying maximum negative charge therefore it would show maximum synergistic bonding due to which C–O bond length would be maximum.

Which of the following has longest $C - O$ bond length? (Free C-O bond length in $C O$ is $1.128 \circ A$ .)
$N i (C O)_{4}$
$[C o (C O)_{4}]^{⊖}$
$[F e (C O)_{4}]^{2 -}$
$[M n (C O)_{6}]^{+}$

$[F e (C O)_{4}]^{2 -}$ has longest $C - O$ bond length. Since in the complex metal atom is carrying maximum negative charge therefore it would show maximum synergistic bonding due to which $C - O$ bond length would be maximum.
