Which of the following species has a linear shape?

A)  \[NO_{2}^{-}\]                       

B)  \[S{{O}_{2}}\]

C)  \[NO_{2}^{+}\]         

D)       \[{{O}_{3}}\]

Correct Answer: C

Solution :

\[\overset{+}{\mathop{N}}\,{{O}_{2}}\] has linear shape due to sp-hybridisation of N of \[N{{O}_{2}}\]

\[O=\overset{+}{\mathop{N}}\,=O\]

While \[S{{O}_{2}},\,NO_{2}^{-}\] and \[{{O}_{3}}\] have angular shape
