                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
