QNEET-2016-Ch-1050: NEET 2016 Chemistry - Class 12 NEET-2016-Ch-1050 Solution: Which of the following has longest C-O bond length? (Free C-O…

Which of the following has longest C-O bond length? (Free C-O bond length in CO is 1.128 A˚\text{\AA}.) [Fe(CO)4]2−[Fe(CO)_4]^{2-} [Mn(CO)6]+[Mn(CO)_6]^+ Ni(CO)4Ni(CO)_4 [Co(CO)4]−[Co(CO)_4]^-

Multiple Choice Options

  • A [Fe(CO) 4 ] 2 −- _
  • B [Mn(CO) 6 ] +
  • C Ni(CO) 4
  • D [Co(CO) 4 ] −- _

Step-by-Step Verified Solution

[Fe(CO) 4 ] 2 _ has the lowest C�O bond order means the longest bond length. Since metal atom is carrying maximum �ve charge therefore it would show maximum synergic bonding as a resultant C�O bond length would be maximum.
