Which of the following can participate in linkage isomerism ?

Options

A. `NO_(2)^(-) `
B. `H_(2) overset(..)NCH_(2)CH_(2) overset(..)N H_(2) `
C. ` H_(2)O`
D. `: NH_(3)`

Answer

A

Explanation

`NO_(2)^(-)` can participate in linkage isomerism because it may bond to metal through nitrogen or through oxygen .
e.g `[Co(NH_(3))_(5) NO_(2)]Cl_(2) ` pentaminenitro cobalt (III ) chloride
and ` underset("pentaminenitrito cobalt (III ) chloride ")([Co(NH_(3))ONO]Cl_(2))`
