Question
Among the following metal carbonyls, the C - O bond order is lowest in
Options
A.[Mn(CO)6]+
B.[Fe(CO)5]
C.[Cr(CO)6]
D.[V(CO)6]-
Solution
(A) Mn+ = 3d54s1 in presence of CO effective configuration = 3d64s0.
Three lone pair for back bonding with vacant orbital of C in CO.
(B) Fe0 = 3d64s2 in presence of CO effective configuration = 3d8 four lone pair for back bonding with CO.
(C) Cr0 = 3d54s1
Effective configuration = 3d6.
Three lone pair for back bonding with CO.
(D) V- = 3d44s2 effective configuration = 3d6 three lone pair for back bonding with CO.
Maximum back bonding is present in Fe(CO)5 there for CO bond order is lowest here.
Three lone pair for back bonding with vacant orbital of C in CO.
(B) Fe0 = 3d64s2 in presence of CO effective configuration = 3d8 four lone pair for back bonding with CO.
(C) Cr0 = 3d54s1
Effective configuration = 3d6.
Three lone pair for back bonding with CO.
(D) V- = 3d44s2 effective configuration = 3d6 three lone pair for back bonding with CO.
Maximum back bonding is present in Fe(CO)5 there for CO bond order is lowest here.
