Out of `N_(2) O , SO_(2), I_(3)^(+), I_(3)^(-), H_(2)O, NO_(2)^(-) and N_(3)^(-)`
the linear species are

Options

A. `NO_2^(-), I_3^(+) , H_2O`
B. `N_2O, I_3^(+), N_3^(-)`
C. `N_2O, I_3^(-) , N_3^(-)`
D. `N^(3-), I^(3+), SO_2`

Answer

C

Explanation

`N_2O : bar(N) + overset(+)N = O`
`I_3^(-) :` with 2 bp and 3 lp around central atom is linear
`N_3^(-)` : with 2 bp (stereoactive pairs) around the central atom is linear.
