Which of the following can participate in linkage isomerism ?

Options

A. `NO_(2)^(-)`
B. `H_(2)overset(••)(N)CH_(2)CH_(2)overset(••)(N)H_(2)`
C. `H_(2)O`
D. `""_(•)^(•)NH_(3)`

Answer

A

Explanation

`NO_(2)^(-)` may be bonded to metal through nitrogen (nitro) or through oxygen (nitro). Hence `NO_(2)^(-)` can participate in linkage isomerism.
