    Which of the following gas is linear?

    A)  \[C{{O}_{2}}\]

    B)  \[S{{O}_{2}}\]

    C)  \[N{{O}_{2}}\]

    D)  \[S{{O}_{3}}\]

    Correct Answer: A

    Solution :

    Key Idea: The molecule having sp hybridization will have linear shape. \[\because \,\,S{{O}_{2}},\,\,S{{O}_{3}}\] and \[N{{O}_{2}}\] have \[s{{p}^{2}}\] hybridisation. \[\therefore \] They are triangular planar in shape. \[\because \,C\] in \[C{{O}_{2}}\] is sp hybridised. \[\therefore \,\,\,C{{O}_{2}}\] is linear in shape.
