Which of the following species is not expected to be a ligand?A. `NO`B. `NH_(4)^(+)`C. `NH_(2)CH_(2)CH_(2)NH_(2)`D. `CO`

Which of the following species is not expected to be a ligand?A. `NO`B

1.	Which of the following species is not expected to be a ligand?A. `NO`B. `NH_(4)^(+)`C. `NH_(2)CH_(2)CH_(2)NH_(2)`D. `CO`
Answer» Correct Answer - B Ligand must donate a pair of electron or loosely held electron pair to metal and form a M-L bond. e.g., `:overset(..)(N)=O, overset(..)(N)H_(2)CH_(2)CH_(2) overset(..)(N)H_(2), :CO`, Among `overset(+)(N)H_(4)` does not have any pair of electron. Hence `overset(+)(N)H_(4)` is not a ligand.
