  • question_answer
    Carbon suboxide \[{{C}_{3}}{{O}_{2}}\] has [DCE 2003]

    A) Linear structure

    B) Bent structure 

    C) Trigonal planar structure

    D) Distorted tetrahedral structure

    Correct Answer: A

    Solution :

    Carbon suboxide has linear structure with \[C-C\]bond length equal to \[130\ {\AA}\] and \[C-O\]bond length equal to \[120\ {\AA}\]. \[O=C=C=C=O\leftrightarrow {{O}^{-}}-C\equiv C-C\equiv {{O}^{+}}\]
